PCAOM - driver and accesoires

This series of Acousto-Optic Modulator Systems consists of High Speed AO Modulators and RF Drivers ideal for use in high speed shuttering applications or optical pulse generators. These systems use high efficiency antireflection coated TeO2 modulator crystals. An optionally available AR coated input/output coupling optics is mounted in an integral precision alignment assembly for optimum focussing of an input laser beam and recollimating of the deflected output beam. The combination of high RF carrier frequency and optimum lens design results in a large angular separation of up to 65 milliradians between the zero and the first order deflected output beams. This makes it easy to separate the two beams in space and maintain a static contrast ratio of at least 500:1.

 Driver model numbers after the dash indicate power output in watts, Digital or Analog Modulation, System or Module, and "SY" designation indicates frequency generation by a synthesizer. All RF Drivers incorporate the latest state-of-the-art semiconductor technology and are burned-in at the factory for a minimum of 24 hours to ensure reliability

 Requirements for the Power Unit:

A simple stabilized 24V / 20VA power unit is required to operate the device. No-load voltage should not exceed 28V, and operational current must not drop below 20V when the device runs under load conditions.

 Additional features:

The plastic housing has the same bores as the PCAOM and avoids earth loops and a thermal interconnection to the optical terminal, which increases operational safety and reliability. The device is also equipped with reverse voltage protection and thermal protection.

 Operation:

After 7 – 8 minutes of warm-up, the PCAOM/heating element has reached its final temperature of 40°C. Now the synthesizer can be adjusted. An increase in efficiency of 3 – 5% has been observed with a surrounding temperature of 20°C.

Important:

The difference between a warmed-up device (efficiency factor: 80-85%) and a cold device (efficiency factor: 20-25%) is 60%!

• INTRODUCTION TO ACOUSTO-OPTIC MODULATORS AND DEFLECTORS:
Acousto-optic components are typically used internal or external to laser equipment for the electronic control of the intensity (modulation) and or position (deflection) of the laser beam. Interaction of acoustic waves and light occur in optical materials when the acoustic wave generates a refractive index wave, which acts as a sinusoidal grating in the optical material. An incident laser beam passing through this grating will be diffracted into several orders. With appropriate design of the modulator or deflector and proper adjustment of the incident angle between the laser light and the axis of acoustic propagation in the optical material (Bragg angle), the first order beam can be made to have the highest efficiency. The angle, (?), the light is diffracted is defined by the equation: aaV?f?== 2?b (1)
Where: ? is the optical wavelength in air
Va is the acoustical velocity of the material
fa is the acoustic frequency
?b is the Bragg angle
This is the angle between the incident laser beam and the diffracted laser beam, with the acoustic wave direction propagating at the base of the triangle formed by the three vectors. A diagram of the relationship between the acoustic wave and the laser beam is shown in figure 1.
The intensity of the light diffracted is proportional to the acoustic power (Pa), the figure of merit (M2) of the optical material, electrode geometric factors (L/H) and inversely proportional to the square
of the wavelength. )Pa)M)HL(?2(57.1(Sin Eff1/2222= (2)
ACOUSTO OPTIC MATERIAL SELECTION
A variety of acousto-optical materials are used for Acousto Optic Modulators depending on the laser parameters such as wavelength, polarization, and power density. Table 2 is a summary of the properties and figure of merit for most common materials used for the NEOS Technologies acousto optical modulators. For the visible region and near infrared region, the most common modulators are made from dense flint glass, fused Silica, crystal Quartz, Tellurium Dioxide, or chalcogenide glass. At the infrared region, Germanium is the most common material with a relative high figure of merit. Lithium Niobate and Gallium Phosphide are used for high frequency signal processing devices.

ACOUSTO-OPTIC MODULATOR CONSTRUCTION
Once the acousto-optic material is selected, it is optically polished. The surfaces of the material that are to be the optical windows are optically AR coated to reduce optical reflections. NEOS uses multi-layer dielectric broadband or “V” AR coatings on the AO modulator optical windows. Typical losses are from a few percent for external cavity devices to 0.2 percent for intra-cavity devices. The side of the material that the acoustic energy is to originate from has a Lithium Niobate transducer metal vacuum bonded to the modulator medium. The transducer converts RF energy applied to it into acoustic energy. Metal bonding provides very good acoustic coupling and NEOS uses only high quality metal bonds. Then the transducer is lapped to the fundamental resonant frequency such as 80 MHz. The top surface of the transducer is then metalized with the transducer shape and size defined in this process. The modulator is then tuned to match the electrical impedance of the RF driver, which will supply the RF energy at the frequency of the transducer’s resonant frequency.
.
RF DRIVER CONSTRUCTION
The RF driver is typically a fixed frequency oscillator and usually consists of a crystal oscillator, an amplitude modulator with an interface, which accepts input modulation, digital and / or analog, and a RF amplifier, which supplies the AO modulator with the level of RF power needed to achieve the highest diffraction efficiency. The specifications brochures on our web site describe the performance of the modulator and driver systems in detail.

DIGITAL MODULATION AND LASER BEAM SHUTTERING
An acousto-optic modulator can be used to shutter a laser beam on and off. By applying a digital TTL signal to the modulator’s driver digital modulation input, the RF energy applied to the modulator is modulated on and off. To support the on-off signal, the rise time of the modulator system has to follow the digital waveform transition. The limit of the acousto-optic modulator rise and fall time is the transit time of the acoustic wave propagation across the optical beam. The rise time is given by:
Va1.5DIA =tr (3)
A typical rise time for a 1 mm diameter laser beam is around 150 nanoseconds. To achieve faster rise times, it is necessary to focus the laser beam through the modulator and decrease the acoustic transit time. A schematic of the focused modulator setup is shown in Figure 1. Since the incident beam is a convergent instead of a collimated beam, the diffraction efficiency decreases as the ratio of the optical beam convergence and the acoustic beam convergence angle increases. For those interested in the design procedure for a wide bandwidth acousto-optic modulator, refer to reference

ANALOG MODULATION
A acousto-optic modulator has a nonlinear transfer function, and as a result, care must be exercised when applying an analog modulation signal to a acousto-optic modulator. For simple gray level control, the best approach is to characterize the transfer function and apply the appropriate voltage levels into the driver’s analog modulation input port. For sinusoidal modulation, a bias is required to move the operating point to the linear region of the transfer function and focussing may be necessary to ensure that the rise time is adequate. The modulation transfer function model is given by Figure 3.
))fo1.2 fm(.(exp2-=MTF: tr .35fo= (4)
where fm is the modulating frequency
The modulation contrast ratio can also be obtained from experimental measurements:
min) I max I ( min) I -max I (+=MT (5)
Where I max = max laser intensity measured.

I min = min laser intensity measured.

CONTRAST RATIO
The contrast ratio is defined as:
min Imax ICR=, for the first order diffracted beam (6)
In the DC case, I min consists of contributions of the scattered light and of light leakage due to the extinct RF power driving the modulator. For maximum contrast ratio, l max must be optimized. This is done by maximizing the diffraction efficiency of the acousto-optic modulator through careful adjustment of the Bragg angle and optimizing the RF drive power. Application of too much RF drive power causes the diffraction efficiency to be reduced. Light leakage (I min) due to the extinct RF power driving the modulator can be reduced by changing the driver’s operating frequency to an idle frequency when the light is desired to be off, there by, the residual light can directed away from the optical path. The DC scattered light can be reduced by use of a beam block. An optimized DC contrast ratio is between 500:1 and 1000:1.
For higher modulation rates, the contrast ratio is reduced due to the loss in diffraction efficiency from the application of the required lens to focus laser light to the needed smaller spot size to achieve the needed rise and fall time in the acousto-optic modulator. Also, l min increases and I max decreases as the modulation frequency increases as both the modulator’s frequency response and the RF driver’s frequency response degrades in performance due to rise and fall time. (eq. 4)
APPLICATIONS OF ACOUSTO-OPTIC MODULATORS:
Acousto-optic modulators can perform other tasks in modulating the laser beam in addition to digital and analog modulation. By careful design, a special class of Acousto optic modulators can be made that modulate more than one wavelength at a time. This will be discussed is the following section on AOTFs and PCAOMs.
By coupling the laser light into and out of the modulators with a fiber optical cable, the modulators can be used as a switch in the communications industry. This will be discussed is the section on fiber optical interface to acousto-optic modulators
By careful broadband design of the transducer and by varying the frequency of the drive signal, the angle that the laser beam is deflected will change. Deflection of the laser beam will be discussed in the section on Acousto-Optic Beam Deflectors (AOBD).
5
When the laser beam passes through the Acoustic wave in the acousto optic material, the interaction causes the frequency of the light (Wavelength ?) to be shifted by an amount equal to the acoustic frequency. This frequency shift can be used for heterodyne detection applications, where precise phase information is measured and can be use to measure distance and velocity accurately.
An AO modulator, called a Q-Switch, typically operating internal to the cavity of a CW pumped Nd:YAG lasers produce greater than 10 kW power pulses with pulse widths of 40-200 nanoseconds wide and repetition rates of up to 100 KHz.
An AO modulator, called a Cavity dumper, typically operating internal to a Ar+ laser cavity produces peak power around 100 Watts and a pulse width of 15 nanoseconds and has a repetition rate of up to 1 MHz.
An AO modulator, called a Mode locker, typically operating internal to a Titanium Sapphire laser cavity modulates the laser at the resonance frequency of the laser cavity, causes the longitudinal modes of the laser to be in phase. This produces very narrow laser pulses having less than 100 femtoseconds pulse width and typically with peak power of around 150 kW.

ACOUSTO-OPTIC TUNABLE FILTERS (AOTF) AND
POLYCHROMATIC ACOUSTO-OPTIC MODULATOR SYSTEMS (PCAOM):
A normal AO modulator is designed to modulate only one wavelength of laser light as the Bragg angle must be changed for any other wavelength of light. A special class of modulators has been developed to modulate multi-wavelength or white light lasers. These modulators are known generally as Acousto-Optic Tunable Filters or by the light show industry, as Poly-Chromatic Acousto-Optic Modulators, and is based on the work of I. C. Chang [8] using Tellurium Dioxide (TeO2) crystals in the slow shear mode. The wavelength tuning curve for these modulators are shown in figure 4. FREQUENCY (10 MMz / DIVWAVELENGTH (
microns)
Figure 4
The angle between the diffracted beams for the different wavelengths is 2.5 degrees for a normal TeO2 device. By designing a small prism to compensate for the angular variation, and by taking advantage of the dispersion property, the net angular deviation of the different wavelengths diffracted is reduced to .002 degrees. Since this is within the normal beam divergence of the laser beam, the output can be considered to be co-linear. This allows one PCAOM modulator to be used in the light show industry to modulate the multi-wavelength lasers instead of using several different modulators, one for each wavelength. NEOS produces several models of the PCAOM modulator for use in the visual spectrum.

THE IDEAL PCAOM SHOULD HAVE THE FOLLOWING CHARACTERISTICS:
1) Large acceptance angle. This allows for alignment insensitivity to movement and allows for
good performance with diverging beams.
2) Narrow optical bandwidth. This allows for rejection of neighboring wavelengths that will
prevent chromatic cross-talk.
3) High throughput efficiency. This prevents one from having to generate excessive RF power in
order to achieve acceptable levels of throughput.
4) Low RF drive frequency. This prevents acoustic losses that are more prevalent at the higher
RF frequencies.
5) Light polarization. Ideally this should be vertical to the mounting surface since most lasers
have their light output oriented in this direction.
6) Small optical cell size. TeO2 is an expensive optical material so using less will result in a lower cost PCAOM.
The following discussion considers the different tradeoffs in the design of two NEOS PCAOMs. The NEOS on-axis acoustic wave PCAOM 48062-2.5-.55 is compared to an off-axis acoustic wave 48058-2.5-.55 PCAOM design. Issues to be reviewed in the in the chart below include filtering bandwidth, throughput efficiency, RF drive frequency, optic cell size, light polarization, and acceptance angle.

The advantage for the light show industry lies with the NEOS 48058-2.5-.55 PCAOM, as one of the most important operating parameters is acceptance angle. Having a narrow acceptance angle causes problems with optical alignment in the field. Each time a system incorporating the PCAOM is shipped or moved, slight movements of the PCAOM can occur. This can result in a degradation of the throughput efficiency and thus require realignment and adjustment for Bragg angle. The design for the 48058-2.5-.55 PCAOM is more tolerant to misalignment caused by movement during setup in the
8
field. Also, the narrow acceptance angle of the 48062-2.5-.55 would require a more collimated laser beam to prevent additional throughput losses experienced when using the more divergent, higher power laser used for light shows.
The apparent disadvantage for the 48058-2.5-.55 PCAOM however, is with the optical bandwidth. This leads to chromatic cross talk between neighboring wavelengths. Test data was plotted showing the level of cross talk for each operating wavelength typically available out of an Ar+/Kr laser. Even though the 48062-2.5-.55 has a worse case cross talk of 10%, it is in the red wavelengths that are less eye sensitive, while the 48058-2.5-.55 has a worse case cross-talk of 25% and 11% in the more eye sensitive green. Of course the cross talk was measured with the light level being referenced against the selected wavelength. Operating at 520 nm out of a typical Ar/Kr laser one observes a worse case condition of having the 520 nm line being 20% of the 514 nm line’s intensity. Then the resulting cross talk becomes 20% of the 25% 514nm cross talk indicated above or 5%, which is reasonably dim. However, the 514 nm line out of a typical Ar/Kr laser is one of the strongest in intensity so the 11% 520 nm cross talk is referenced against a bright line and therefore will show significant visibility.
The whole cross talk issue above is academic if one realizes that many light display systems use a three-color RGB configuration. In this situation, any amount of cross talk between 514 and 520
will be negated since both of these green lines will be turned on simultaneously during light shows.
A description of the design and performance of a NEOS 48062-2.5-.55 PCAOM and a 48058-2.5-.55 are given below:
RF DRIVE POWER
Due to the high figure of merit for Teo2, the drive power required to achieve up to a 85% efficiency per wavelength is low. Table1 below list the drive power for several wavelengths for both the 48062 and the 48058 PCAOMs.

OUTPUT ANGLE AND VARIATION AS A FUNCTION OF WAVELENGTH
The deflection angle between the wavelengths is 2.5 degrees for a standard TeO2 Modulator. By properly designing a small prism to compensate for the angular variation, the net angular deviation of the diffracted beams is reduced to 0.002 degrees. This is a very small angle and, therefore, the output is collinear. The addition of this prism results in the output beam being displaced by 4.5 degrees from the input beam for the 48062-2.5-.55. For the 48058-2.5-.55 the output beam is displaced by 1.4 degrees.
SPECTRAL RESOLUTION
The closest laser lines in an Ar+ laser is 6 nm apart. Figure 5 shows the measured response for the 48062 PCAOM. Figure 6 shows the measured response for the 48058.

The 48062 PCAOM shows a spectral line width of about 1.7 nm at 514 nm and for the worse case (longest wavelength) is 4.0 nm. The 48058 PCAOM shows a spectral line width of about 2.3 nm at 514 nm and for the worse case (longest wavelength) is 7.5 nm.
INPUT ACCEPTANCE ANGLE
The input acceptance angle for the 48062-2.5-.55 PCAOM is <1 mrad (solid angle). Although this angle is fairly tight, alignment is similar to standard AOMs. For the 48058-2.5-.55 PCAOM the acceptance angle is ? 30 mrad (solid angle) allowing easy alignment of the device in the optical system.
TEMPERATURE VARIATION
The PCAOM is sensitive to temperature. The measurements show a sensitivity of 10 to 16 KHz per 0C. Since a 3 dB bandwidth of the PCAOM is about 200 KHz, a + 5 0C variation can be tolerated.
POWER HANDLING CAPABILITY
The typical laser used in the light show industry produces 20 Watts optical power. When the crystals have impurities, the effects are seen as blooming (thermal lensing) in the output beam. All of materials selected for making the NEOS PCAOMs are for high power operation.
11
OPTICAL EXTINCTION RATIO
The extinction ratio is very important. Careful design of the RF driver provides a good extinction ratio of typically more than 40 dB in the image plane modulated and with blanking, the extinction ratio is greater than 60 dB.
PCAOM MODULATOR DRIVERS
The PCAOM driver is designed to generate the needed RF frequencies to select the desired output wavelengths with a 0 to 5 Volt AM input and TTL blanking signal and can be driven directly from a computer. Crosstalk is at least 20 dB down optically between wavelengths. Frequency stability is .01%, 0 to 600 C for our frequency synthesized 8 channel (8 selectable optical frequencies) drivers and the frequency can be tuned in 8 KHz steps to accommodate for any temperature changes in the PCAOM. The NEOS PCAOM drivers are made in 4 and 8 channel systems (rack mountable box) and OEM modules.
APPLICATIONS OF THE PCAOM AND AOTF
The PCAOM is a perfect Modulator for the multi-wavelength Argon ion laser or the Krypton-Argon laser used in the laser light show applications. The NEOS PCAOM devices come in standard and weather-proof cases.
Applications for the AOTF modulators include fluorescence spectroscopy and medical applications and can be made for wavelengths from 0.4 µm to 5 µm. Large aperture AOTFs are available up to 25 mm.
FIBER OPTICAL INTERFACE TO ACOUSTO-OPTIC MODULATORS:
Many of the key characteristics of acousto-optic modulators make them ideal for use in fiber optical applications. NEOS has developed a family of modulators, which are fiber coupled. 2, 3 and 4 port modulators allow for digital switching of optical path, analog modulation (Attenuation), and frequency shifting applications. NEOS’ fiber coupled modulators are available as OEM modulators with drivers and systems (AO modulators and drivers integrated in one package).
FIBER OPTICAL APPLICATIONS
Applications of fiber coupled acousto-optic modulators include: Characterization of gain performance of optical amplifiers and long distance optical fiber communications, laser linewidth measurement, low noise signal transmission, and tunable filters for WDM applications. See the references listed for details. [9 - 20]
12
ACOUSTO OPTIC BEAM DEFLECTORS:
Acousto-Optic Beam Deflectors (AOBD) are used to control the position of a laser beam as well as modulation. By careful broadband design of the transducer and by varying the frequency of the drive signal, the angle that the laser beam is deflected will change. The AOBD typically deflects the laser beam over a fraction of a degree to a couple of degrees with a resolution of a few hundred spots to an upper limit of about two thousand spots. Typical diffraction efficiencies are 40-70 percent.
AOBD OPTICAL AND ELECTRICAL SYSTEM SETUP
A schematic setup of the AOBD and drive electronics is shown in Fig. 7.
VCO or DFSRF AMPCONTROLELECTRONICSAOBDINPUTBEAMFOCALPLANEINPUT AOBD SYSTEM CONFIGURATION
FIGURE 7
13
One of the AOBD’s physical characteristics of concern in an optical system design is its optical aperture dimensions optical height (H), and the width (D). Usually, the optical width is much larger than the height because of performance and design constraints. As a result, the input and output optical laser beam will require cylindrical optics to transform the incident laser beam from a circular beam to a truncated profile rectangular beam, and then back to a circular beam after the deflector. The output optics usually focuses the deflected circular beam to a line of focused spots in the output plane. NEOS has developed a special group of slow shear wave Tellurium Dioxide (TeO2) crystals deflectors that accepts a circular laser beam and does not need cylindrical lens transformation. This can simplify many applications.
AOBD DESIGN EQUATIONS
In the section on acousto-optic modulators, there is a presentation on acousto-optic material selection, angular deflection vs. input RF frequency, and diffraction efficiency. These calculations are also valid for the AOBD.
GENERAL DEFINITION ON OPTICAL DEFLECTOR RESOLUTION
Optical deflectors, whether they are mechanical or solid state in nature, obey the same fundamental equations for resolution. Assume the deflector aperture is D. The natural divergence of a collimated laser beam of width D is equal to:
D?=?? (7)
If the total scan angle of the deflector is defined as ??, then the total number of resolvable spots is:
?=?? ?N (8) ??D ?=
The above equation holds for all deflectors. Now, this equation is applied to the AOBD.
The total angular sweep of the AOBD is:
VaFa ????= (9)
? is the optical wavelength
? Fa is the acousto-optic bandwidth
Va is the acoustic velocity
Examples of typical AOBD scan characteristics are shown in figure 10 at the end of this document.
14
Now substitute ? into the resolution equation. Then,
Va?FaDN= (10)
= ? Fa x ?T
Or in other words, the number of resolution elements N, is equal to the aperture time ?T of the AOBD multiplied by the acousto-optic bandwidth ? Fa, (commonly known as Time Bandwidth product ). The value N is obtained with uniform illumination of the aperture D. When the output of the deflector is focused to a spot, the neighboring spots are such that the peak of one intensity spot is on the first zero intensity of the neighbor. The two spots cross over at the 40% intensity points, and the spot profiles are shown in Fig. 8. There are several factors that will degrade the total number of resolution elements, and these will be discussed below.
FIGURE 8
MODULATION TRANSFER FUNCTION F? ?
When dealing with laser deflection or scanning of an entire line or frame, it is necessary to consider the modulation transfer function or the contrast ratio. A parameter p, the truncation ratio of the laser beam illuminating the AOBD, is defined as:
p = D/W (11)
where W is the diameter of the laser beam at the1/e2 intensity points
15
A plot of the modulation transfer function is shown in Figure 9. For example, with p = 0, (uniform illumination) and an MTF of 0.5, the maximum number cycles per line is equal to ? Fa x ? T/2. With p = 1, the intensity drops to 1/e2 at the ends of the aperture. The resolution in cycles per line is about ? Fa x ? T/2.1
FIGURE 9
SCAN FLY BACK TIME
Since it takes a finite time for the acoustic energy to fill the AOBD, the total number of resolvable spots is reduced to:
)a?T?Fa)( T-TT-(1 N??= (12)
Where: T is the total linear FM scan time
“a” is parameter for uniformity of illumination
a = 1 for uniform beam illumination
a = 1.34 for gaussian beam illumination
CYLINDER LENSING EFFECT
The linear FM modulation in the AOBD produces a lensing effect in addition to deflection.
The focal length (FL) of the acoustic lens is given by:
)dtdFa(?VaFL2•=a (13)
Where dtdFais the FM slope.
This lensing effect must be taken into the design of any optical system using an AOBD. This lensing effect can also be useful in some applications.
16
AOBD APPLICATIONS:
A variety of operations can be performed with these devices: They include single axis (1 D) and two axis (2 D) laser beam deflection and optical signal processing. The electronics for the deflector are arranged in one of three ways depending on the application. First, for continuous laser beam deflection, the deflection angle is directly proportional to the RF frequency. Therefore, a linear voltage controlled oscillator (VCO) or a digitally frequency synthesizer (DFS) is used to drive the RF amplifier for the AOBD. For a continuous line scan, a linear sawtooth waveform drives the VCO, outputting a linear FM signal. Since the frequency linearity is extremely important, it is necessary to have additional digital electronics to correct for small non-linearity of the VCO. This signal will drive the AOBD to output a line scan. The scan rate is limited by the scan fly back time (eq. 12) and the lensing effect (eq. 13).
In the second application where vector (random) scanning is needed, then the electronic input is usually a digital word, which causes a different frequency to be output for each word. The location of the AOBD output beam is represented by the digital word. A D/A circuit converts the digital signal to an analog signal, and the analog signal in turn drives the linear VCO. With this electrical input, the AOBD deflects the laser beam to a specific point in the output plane. To address the next location, consideration must be given to the minimum access time which is equal to the sum of the AOBD aperture time (D / Va) plus the electronics retrace time.
In the third application, for signal processing, the AOBD or Bragg cell is driven by an input RF signal from an amplifier which beings the signal of interest to the appropriate RF power level for the best performance of the AOBD. Typical signal processing involves spectral analyst of the input signal for frequency information or presence or detection of a specific signal; correlation to the presence of specific signal; tempest testing, where the original signal can not be present in the encoded signal, and radar signal analysis for ambiguity.
NEOS AOBDs are typically made of TeO2 which are ideal for 1D or 2D scanning and signal processing. For more detailed analysis of the AOBD, refer to the references. NEOS Technologies can assist you in answering technical questions in regard to acousto optics.

Fibre systems  

Strict requirements concerning flexibility and mobility of laser units have been the reason for the development of the Laser-age beam piloting units, and these units have undergone continuous perfection for various applications.

The LASERAGE glass fibre systems developed by OMICRON today define the standard for the application of beam piloting units and have been especially designed for external operation of laser projection equipment. A number of various optical systems let the fibre system adapt to nearly any conditions and let almost any dream come true. No matter if you require a laser for a theatre or for industrial purposes, for clinics or for outdoor projection equipment – there is a solution for all such applications.

Compact design, high precision, perfect long-term reliability, excellent transmission features, quick and exact adjustment, extremely flexible.

The laser beam piloting unit consists of an connector with setting options to position the fibre and a focus adjustment feature to optimise the position of the beam at the end of the fibre. The exactness of the setting is better than one micrometre. The standard diameter of the fibre is 50 micrometres. However, there are also fibre diameters of between 5 and 200 micrometers available. Optionally the fibres can be protected with an flexible metal tube.

with a collimating optical system. The standard optical system generates a beam with a diameter of about 2.5 millimetres and a divergence comparable to the laser source.  For short-distance applications, collimators for smaller diameters are also available. If the area capacity has to be as low as possible or should the customer request low divergence - OMNICRON has developed special optical systems even for such applications.

The optical fibre system has a remarkably high efficiency factor:  there are nearly no losses for the transmission of the laser light with a fibre length of 10 metres and a TEM00 output mode of the laser. The standard programme offers lengths of up to 200 metres, and, of course, the LASER-age beam piloting units can be integrated into any already existing systems.

LASER CONTROL LASER EFFECTS AND GRAPHICS WITH ANY LIGHT PANEL DMX-512
Preparing light show with lasers? You need a DMX-NOVA.
DMX-NOVA allows you to monitor and control the effects of laser and light with a standard DMX light control panel. With the DMX-NOVA lighting designer can organize a laser-light show in a very short time. For the first time in history, was the possibility of creating a unique atmosphere of light and laser effects without the need for complicated programming controllers lasers. The Lord of Light has now become King of lasers.
DMX-control unit NOVA has two possible settings:
The emulation mode imitates the function of the light channel 12 mobile (for example, Super Zoom Scan). Control of laser effects like a moving light control.
Here are a few examples of setting different channels in emulation mode:
• Iris Control - maintains and enhances the effect of the laser
• Select 1020 graphics special effect
• The basic colors - red, green and blue (RGB) colors determine the image
• The COLOR choose different color effects
• PAN and TILT (which features moving planes) changes the position of visual effects
• The PRISM (or prism) creates clones of the main graphics
• ZOOM and FOCUS functions (ie, zoom in and zoom out) change the image size.
A few additional channels are reserved for functions such as image rotation, text and animation features.
To get the best results working with DMX-NOVA LASERAGE mode has been introduced. This mode, called in short LA-mode can coordinate 32 channels 8-bit as well as 16-channel extension. This allows the user to select a variety of special effect functions (for example, video animations, presentations, text, modulation effects, morphing, three-dimensional rotation, painting a picture, and zoom functions, and mute).

? by Omicron, FK-LA5000 Lasers 6/43

System components:

The laser-head is connected with two multipin-cables to the power-supply-unit.

To run the system you require a power-source, power-cord, the laser-head, powersupply

and the signal- and high-power SUB-D-cables.

The power-supply contains all parts to regulate the laser-current, laser-temperature

and second-harmonic-generator temperature (“S.H.G.”- or “NLO”- temperature). The

diode- and SHG-temperature is not for user-adjust. The output power is adjustable.

The laser-head contains the laserdiode, thermo-electrical coolers, and sensorelectronics

for temperature-sensing.

If the two SUB-D cables are combined between the power-supply and the laser-head,

all important electrical connections are combiened. In case of a bad connection the

laser-system is reacting with a jump into a safe state. All states will be indicated to the

user. For solving system-operation problems very quick, please tell your service

engineer the indicated readings displayed on the front of the power-supply.

The laser-system does not need a remote control because of a very compact design.

If the remote function is needed there is an control option available through an RS232

interface and a PC-software remote control.

This option is not included in the basic system. The RS232 interface needs to be

ordered extra when the system is delivered the first time. There is an update-kit

available to update the laser-system to RS232-control later on.

The laser-head has also an option to modulate the laserpower directly with an

analogue voltage from 0-5V or 0-10V.

This option is not included in the basic system. The modulation-interface need to be

ordered extra when the system is delivered the first time. There is an update-kit

available to update the laser-system to external modulation-control later on.

CAUTION:

Before connecting the system to an electrical power-source, please make sure all

units are well connected and the operation of the system is fully understood.

System Introduction, Controls, Indicators and Connections:

The FK-LA 3000/5000 advantages are:

• 5W cw @ 532nm, from a max. 600Watts power-source

• Operation on AC- or DC-voltage sources. (105V-310VDC / 85VAC-265VAC)

• high conversion efficiency on very flexible power-requirements

• low cooling consumption, aircooled, no additional chiller needed

• quick power on and boot-up of the power-supply and its regulation parameters

(output of 95% of laserpower in less than 5sec after turn on / 100% after 2min.

of heat-up time)

• low weight and less space for installation / easy transportation

• “hands-off” operation

• simple and stable laser resonator-design

• no moveable parts to align

• interfacing to host-computers via RS232 or RS485 with an easy control

protocol (controlable from any RS232 terminal program)

• optional fast direct laserbeam-modulation from 0-100% (option)

• power-factor controlled power-supply (cos?=0.97)

and even more advantages on handling the FK-LA 3000/5000 laser.

The laser-head:

The FK-LA laser-head contains the housing and fixing ground-plate for the laserdiode

and optics (sealed area) and the thermo-electrical coolers including the system

for heat transition to air.

The SHG-crystal and the thin disc is also located in the sealed area of the laser-head.

The laser-head does not need any external power-sources. It is important to run the

laser only with the LA BP-D40 power-supply. If the laser contains a direct modulationdevice

there is another active SUB-D 9way jack located at the backside of the laserhead.

If there is only one cable connected to the power-supply the laser will not start or

immediately shows an error-state. (the red high-temperature-LED and the interlock-

LED is ON)

In case of bad contact from the power-supply to the laser-head, the system might be

working for a few minutes, but when the temperature control is not active, the

lasertemperture is rising. Will the temperature come to the border of the maximum

the saftey circuit is turning off the whole system.

In any case the sensitive laser-diode is protected with saftey circuits, against twistedpoles

and ESD.

During the laser-head is not connected to the power-supply all sensitive devices are

relay-shorted.

EMC: (electro-magnetic-compatibility)

The Laser-head has no major electro-magnetic radiation and the device is also not

very sensitive to electro-magnetic radiation influences coming from the environment.

If the laser comes with an build in direct modulation device, all components are

located in the laser-head, so there is a minimum radiation emitted from the

connection-leads.

Options for the laser-head:

• “fiber coupled”:

there is an update-kit available to upgrade the laser-head with a fibercoupler

that no spread-light appears at the laser-head. All the laser-light

produced from the head will be transmitted with a high-efficient fiber (90%

efficiency) to the place where it is needed.

• “direct-modulation”:

With version 2.0 it is possible to upgrade the laser-head by a directmodulation-

device. The direct-modulation-device enables the laser to run

with an analogue voltage from 0…100% output-power. The modulation

frequency is from DC to max. 25kHz. The direct modulation device is very

useful for lower modulation speed applications.

The power-supply:

The FKL-LA power-supply, LA BP-40D is converting the energy for the laser-head.

The laser-head runs with a very low voltage on a very high current and two different

temperature regulation circuits for two different types of thermo electric cooling

systems. These requirements demanding for an efficient power-supply design.

The LA BP 40D has an efficiency of totally > 80%. The input can be supplied from an

AC or DC voltage source. Selection of different voltages is not necessary.

If the power-supply is operated under 160V AC and 240V DC the input fuse need

to be changed from 6A to 8A.

The main-switch is at the backside of the power-supply turning on all internal devices.

If the keyswitch at the frontside is turned OFF, the power-supply turns ON into a

standby-status. On standby-mode the SHG-crystal will be temperatured and all

control-electronis are powered. The laserdiode-temperature regulator and the lasercurrent-

driver will be activated by the keyswitch. With the laser-ON standby-switch (at

the front of the power-supply) the internal or external settled output-current will be

enabled. The laser-diode is temperatured in all positions of the switch.

? by Omicron, FK-LA5000 Lasers 10/43

In case the temperature is under 15°C or higher than 45°C the power-supply will be

set automatically on standby. This can take a few seconds until the laser-diode

temperature is settled.

If the environmental-temperature is between 15°C and 45°C the laser turns on

immediately.

Power-supply frontview-19”:

Laser-current display:

The laser-current-flow (laser-diode current) is displayed on the big LCD display.

Laser-current manual control:

The laser-current manual control-knob adjusts manually the laser-current.

Manual changes of the current, which can be internal set from the RS232 control

board, will be overridden. The current-control is designed as “the highest takes

priority”.

The highest input-level (from external or internal input-signals) sets the actual currentmodulation.

Laser-standby switch:

The laser-standby switch turns off every input signals, even from the RS232 control,

so the laser-current modulator will be set to 0-Amps.

This switch is not for emergency-turn off. Use the AUX.-Interlock-pins to create an

external Interlock-loop.

Laser-diode and NLO temperature display:

The Laser-diode- and NLO-temperature-display shows the user the specific diode and

NLO temperature. Both temperatures should be set to the specified levels of the finaltest

Turn-key-switch:

The turn-key switch enables the internal power-sources for Laser-diode-current and

TE-Coolers.

Turning the keyswitch ON or OFF will override the RS-232 control ON-OFF

command.

The turn-key can stay at any position when the power-supply is turned off.

DANGER:

Please be careful when the power-supply is turned ON by the main-switch.

The laser will may start on full-power (!) depending on the input levels or the position

of the keyswitch.

To prevent full power-output always turn off the standby-switch. (lower position)

STATUS-LED’s:

Interlock: yellow indicator for open interlock-loop

Laser-Emission: green indicator for possible laser emission

Power On: blue indicator for standby or main-power supply O.K.

AUX-interlock:

The aux-interlock socket is a three-way female mini socket. The pins 1 and 2 are

normally shorted for closed loop interlock.

The connection of pin 1 and 2 to an external interlock loop requires a galvanic

shielded circuit.

Always use contact-opener to close the loop.

Pinning: (frontview)

By activating the AUX-Interlock the error-status will be stored in the error-status-flag.

The flag can only be erased by manually turning off the power-supply or with a

RESET-command from the RS232 control interface.

The activated flag will be indicated with the yellow-interlock LED.

It is not possible to erase the flag, when the yellow-interlock LED and the red temp.-

error LED are active

.

Please contact your customer-service technician for help when non-resetable errors

occur.

external analogue-control-voltage (Standard on vers. 2.0). The control-voltage inputrange

starts from 0…+5V, DC. The input-resistance is min. 10k Ohm. The modulation

speed is max. 10-15Hz.

Generally the slow-power modulation is used in Laser-marking or Laser-display

applications to set individual power-levels. The input is connected to internal GND,

but shielded from housing-screen to prevent hum and noise.

Optional BNC-ext. enable-input:

The external enable-input inverts the front-panel enable-switch.

Looping the pins (pin and ring of BNC-jack) will result the enabled laser status.

For special customer applications, the input is used for switching between idle- and

run-levels.

Laser safety:

The FK-LA 3000/5000 Laser is manufactured in compliance with the international

safety standards EN 60825-1:1993.

The manual contains different safety terms:

The DANGER! label explains danger that could result in personal injury or death.

The CAUTION! label explains hazards that could damage a part of the system or

external instrument. In addition, a NOTE! label will give important informations to the

user of the laser-system. This should help to operate the system correctly.

• DANGER! Before operating the laser-system read the manual carefully to

prevent damage to human persons and animals, integrated devices and

connected devices.

• DANGER! The electrical units should not be operated in hazardous

environment.

• DANGER! Neither the power-supply nor the laser-head contains any

components, which need constant service. Opening the covers during

operation for any internal tuning or component-replacement is not allowed.

Please contact our service-technician for authorized and special-trained

service.

• DANGER! The FK-LA 3000/5000 Laser system should only be opened by

trained-service personnel. In case of any adjustment or replacement of

components, beware of laser radiation during the service procedure.

Always wear safety goggles while the laser emits laser-beams.

• DANGER! Do not look into the beam of the FK-LA 3000/5000 Laser system

under conditions with exceed the limits specified by the international lasersafety

standard EN 60825-1:1993. Take precautions and countermeasures to

diagnose exposure of direct or reflected beam.

• DANGER! The FK-LA 3000/5000 Laser system is an appliance for the

operation of the FKL-laser-head together with the LABP-D40-CW powersupply

for producing 532nm laser-light and thus cannot be regarded as a

separat laser-device at the time of the delivery. Therefore, the user is

responsible for keeping the legal specified protective measurements for lasers

(details like the laser-safety-class, markings on the FK-LA housing, laser

warning systems during operation and operating instructions of the operatingstaff).

• DANGER! Beware of the warning signs and take great care while operating

the powerful FK-LA 3000/5000 laser-system (class 4b).

• DANGER! Before disconnecting the FK-LA 3000/5000 Laser-head from the

power-supply it must be switched off. To prevent the laser against damage,

check all parameters of external signal- and power-sources.

• CAUTION! To prevent the laserdiode, thin-disc or SHG-crystal against

damage, avoid all possible reflections back into the laser.

? by Omicron, FK-LA5000 Lasers 16/43

The safety labels:

The FK-LA laser-head has a protective housing. It is fixed with screws and may not be

opened during operation, except for maintenance and service.

• DANGER! During the housing cover is open, the laser-diode-current must be reduced

to low power (laser-class 1 level) or switched off completely. With the cover open, the

laser may emit stray light which can cause hazards for the eyes and skin. Protective

eye-goggles are necessary! Also avoid direct exposure of the laserbeam to the

surface of the skin.

These labels are fixed at the laser-head according to the EN 60825-1:1993:

1.) Size: 52mm x 26mm, both languages

Colour: yellow/black

2.) Size: 47mm x 42mm

Colour: yellow/black

DANGER! The laser-system emits visible and invisible continuous laser-light of up to

10 Watts of radiation power. (class 4b laser product)

Avoid exposure of the laser beam or laser stray light to eyes and skin.

Installation:

The FK-LA 3000/5000 Laser-system is very easy to setup.

After unpacking and inspection the Laser-head and the power-supply, both will be

connected as shown in the following diagram.

For installation of the FK-LA 3000/5000 Laser-system, the following instructions have

to be observed:

• Environmental conditions: +15°C…+45°C, relative humidity max. 70%, not condensed

• Pay attention to proper air-flow and convection around the housing of the powersupply

and the laser-head. To prevent heat-accumulation of the power-supply there

should be min. 5cm distance to the next 19”-device. Also a ventilation-grid must be

installed in the upper 19”-rack-unit.

• To prevent heat- and dust-accumulation at the optical-bench, the Laser must be

connected with air-pipes to the outside.

• The maximum cable-length between laser-head and power-supply is specified to 2m.

In case other cable-lengths are needed, the laser can be trimmed by the

manufacturer.

• CAUTION! It is not allowed to extend the cable-length by an unspecified person!

Operation:

The FK-LA 3000/5000 laser-system is very easy to operate.

Before connecting the laser-system to the main power-line, make sure all components

are combined the right way.

For the first operation:

(later steps are exchangeable)

• Ensure that the keyswitch is in OFF-position.

• Ensure that the laser-standby-switch is on standby.

• Ensure that the laser-manual-control- knob is turned left to minimum level.

• Turn ON the main switch in the back of the power-supply, the LCD-displays will

light up and the power-ON-LED will glow with blue light.

• Take a look on NLO- and diode temperature. The diode-temp. should be at roomtemperature

and the NLO will heat up to specific operation level.

• By turning on the key-switch, the power-supply enables the energy-source to start

the laser-diode-current and the laser-diode- temperature.

• The diode-temp. will rise or fall to specific level. (depending on start temperature)

• Slowly turn the manual-current-control-knob to the right side. The light-output of

the laser will start, when Laser-current reaches more than 8-Amperes.

• After the working-session is finished, the Laser can be turned off by any trigger.

(manual-, RS-232- or power-off control)

There are the following Error-events:

The system will always restart with a power-ON-reset, there is a “malfunction” in the

system, which is not resetable.

• Laser automatically turns off, Temp. Interlock LED is ON:

Cause:

The cooling air for the laser-head is to warm, or the air-inlet of the laser-head

is covered:

- Ensure for correct air-flow or clear the blocked air-inlet.

- After a few minutes, turn the power-supply ON again.

The temperature-regulator has a malfunction:

- After several turn-ON and OFF procedures, the Laser is not able to operate,

please contact your service-engineer.

• Laser turns off by ext. Interlock:

? by Omicron, FK-LA5000 Lasers 20/43

Release the Interlock-knob or close the Interlock-loop. Turn the keyswitch OFF

and ON again. The Laser will start.

• Laser is on low power, even the diode-current is on maximum level:

Check the NLO and Laserdiode-temp. for their specific-values. If the specificvalues

are different from the specified range, please call for your serviceengineer.

There is no user-adjustabale alignment of the Laser to increase the outputpower.

• Laser is controlled by RS232 control and automatically turns off:

Check the status-information with the “stat1” and “stat2”- RS232 command. In

case a “RESETBAD” – message is returned after “RS”-command, the system has

a malfunction and service is needed. All other errors are resetable.

• Laser does not start, there is no LED ON at the frontpanel:

Check the input-fuse at the back of the power-supply (6/8Amps, 20mm fuse is

required for replacement)

The power-supply contains further fuses. They are located on the “power-block” at

the left and right PCB.

CAUTION:

Please replace fuses only by the same rating.

The damage of a fuse is always a serious malfunction. Contact your serviceengineer

for quick help.

To prevent larger damage, please contact your local dealer.

Do not repair the power-supply without proper information.

• Laser does not start, everything seems to be normal:

Check the cables between the power-supply and the laser-head for proper

connection. Check the cables for loosen wires or bad connectors.

For other errors, please contact your service-engineer.

1. Introduction:

This RS232 control-command specification is to control the FK-LA 3000/5000

laser-system from an external host computer.

It was designed to turn the laser on/off and to set different power-levels. The

three-state operation was developed to create a fast switching state (state 2) for

material-processing-, lasermarking- or entertainment-control. All commands are

designed to make the control as easy as possible.

2. Overview:

The laser power-supply has an RS232 “command interface” which receives

controlling commands for the turned on laser. The external host computer is able

to receive replies to monitor laserdata from this serial port.

In addition, the laser power-supply has an RS232 “debug interface” which is used,

for development purposes only, for downloading firmware from PC to the laser.

3. Physical Interface:

3.1. RS 232 command connector:

The LABP-40 D power-supply has a 9pin D-type socket (female) connector

pin Function signal direction at laser comment

2 TXD / TD -> out already twisted

3 RXD / RD <- in already twisted

5 signal GND <- ->

1,4,6 (DCD, DTR, DSR) shorted together

7,8 (RTS, CTS) shorted together

screen cable shield

9 NC

To connect the laser command RS232-port to the host, a 3-wire screened cable is

required. It should be a non-twisted null-modem cable. The RS232 cable is not

included in the shipment.

The connector provides screwlock features to be secured to the host.

3.2. RS 232 debug connector:

connector.

5 signal GND <- ->

8 (CTS) shorted together

9 NC

To connect the debug RS232 port to the host, a 6-wire screened cable is required. It

should be a non-twisted RS232-modem cable. This RS232 cable is not included in the

shipment.

The connector provides screwlock features to be secured to the host.

There is an in-field update device available, which is a small, self-contained device.

4. Logical Interface:

4.1. Protocol:

The transmission protocol is:

Baud rate 9600 bits per second, 8 data bits, one stop bit, no parity.

There is no hardware handshake or flow control, just null-modem connection.

The host will send “commands” and the laser will send “replies”.

All commands and replies consist of printable ASCII characters, usually ‘A-Z’ and ‘0-9’

and ‘ ‘ (ASCII SPACE) and ‘>’ (ASCII greater-than symbol).

Each command line and reply line ends with a ‘carriage return’ and a ‘line-feed’

(shown as CR/LF).

? by Omicron, FK-LA5000 Lasers 24/43

All commands and reply sequences are case sensitive.

4.2. Commands:

Commands are of fixed length, either 16 bytes, or 4 bytes, including CR/LF.

4.3. Replies:

All host commands will elicit a reply from the laser. The host will not send subsequent

commands until a reply has been received from the laser, unless the timeout period

for the reply has expired, when the host may repeat the command.

If the host does not understand a reply from the laser it will not send anything to let

the laser know that it did not understand.

Replies may be of variable length from 3 to 60 bytes including CR/LF.

If the command involves the laser taking some action then the laser will take action

and then send back the reply.

The design of that logical communication is made to control the laser from easy to use

ASCII-terminal programs (like hyper-terminal)

4.4. Initialising:

The powered laser will perform its internal initialisation and temperature stabilisation

of the NLO and then send out a RESETOK type of reply as if it had received a RESET

command. It will not reply to any commands for up to 30 seconds while initialising. If

the Laser-power-supply is switched on manually the RS232 command for Laser on/off

is overwritten. This is the same for all manually controllable parts of the laser.

Maintenance:

The FK-LA 3000/5000 laser-system contains no major serviceable parts.

Keeping the system clean and dustfree are the most important services.

The laser-head:

Cleaning the cooling-air channel:

After a few months of operation or temp. Interlock problems in good cooling environment

the laser-head should be examined for dust-storage in the cooling channel.

Before cleaning the cooling-air channel, please protect the output-optics with a cover.

Use a pressured air jet (oil- and waterfree) to clean the ventilation and cooling-airlamellas.

After this procedure it is absolutely necessary to check the surface of the laserhead-

output window.

Cleaning the laser-head-output window:

After a few months of operation the laserbeam might get a corona. This corona is due to

some dust-particles on the output-windows.

There are two output-windows: one is at the outside aluminium cover, the other one is

located on the sealed aluminium-housing inside the laser-head.

Under ordinary circumstances the inside window should be clean, so it is only necessary

to clean the outside window from both sides.

The outer window can be removed by releasing the screws.

Open the aluminium-head-cover to clean the inside window.

CAUTION:

Consult your service-engineer before opening the aluminium head-cover. When opening

the aluminium head-cover of the FK-LA laser-system, the legitimate claims for warranty

will expire.

Cleaning procedures:

“Clean” is a relative description; nothing is perfectly clean, and no cleaning procedure

removes contaminants absolutely.

It is a process of reducing objectionable materials to acceptable levels.

The following solvents and papers are allowed:

• Methanol, chemical-free, 99,999% pure solvent

• Acetone chemical-free, 99,999% pure solvent

• Kodak Lens Cleaning PaperTM or equivalent

• Clean (new) finger cots or powder-free latex gloves

• Plastic hemostat for holding the paper

Before cleaning the optical surface with solvent, use dry nitrogen or canned air to blow

dust and lint from the surface (the dust could cost permanent damages by scratching the

extremly sensitive surface-coating).

? by Omicron, FK-LA5000 Lasers 39/43

Usage of methanol and acetone with lens cleaning:

The Lens Cleaning Paper must be folded in a certain way, so that the optical surface of

the window will only have contact with the “untouched-area” of the paper.

Hold the folded lens cleaning paper by a plastic hemostat. Use 2-3 drops of clean

methanol on the lens cleaning paper and wipe off the outside of the output-window by

“one-wipe”. Never use a paper twice.

Repeat the procedure on the other side of the window.

Redo, if the result is not satisfying.

After the pre-cleaning with methanol change the solvent to acetone for “waterfree”

cleaning and follow the same steps as done with methanol before.

When the cleaning is done, you can re-install the output window.

In case the output-corona is still present after you have thoroughly done the cleaning, the

outside of the inner-output-window needs to be cleaned.

The inner-output-window is not removeable un-installation.

The window can only be cleaned in installed condition. Please follow the cleaning steps

as mentioned above.

CAUTION:

Do not open the inner-sealed area of the Laser. The inside is filled with protecticegas.

As soon as the screws are opened, the gas will evaporate.

After cleaning both windows the corona should have disappeared. In case the results do

not satisfy you, please call you service engineer.

The Power-supply:

The power-supply is designed maintenance-free.

During operation, keep the power-supply clean and protect it from liquids and lint.

After a few years of operation the internal-heat sink needs to be checked for duststorage.

Please use a pressured air jet (oil- and waterfree) to clean the ventilation and cooling-airlamellas.

Check the power-supply for propper function after cleaning procedure.

CAUTION:

When opening the aluminium housing of the power-supply on the FK-LA laser-system the

legitimate claims for warranty will expire.

Consult your service-engineer for instructions before opening the power-supply.
