DEFLECTORS

Acousto-optic deflectors (AODF) offer precise angular control of an optical beam using RF drive frequency tuning. Up to two thousand spots can be resolved over an angular range of a few degrees for 1D and 2D scanning as well as beam deflection through a fixed angle. The scan speed can be as fast as a few microseconds.

Uniform diffraction efficiency
G&H deflectors offer highly uniform diffraction efficiency across the full scan angle, with consistent power throughput for scanning applications such as material processing and digital imaging. We manufacture devices based on tellurium dioxide (TeO2) crystals grown in-house for visible and near-infrared (NIR) wavelength applications. For optimal transmission in the ultraviolet (UV) we offer fused silica and crystal quartz products. For broad bandwidth applications, we use a longitudinal mode approach with a phased array of piezoelectric elements within the transducer. We achieve high efficiency with slow shear deflection using parallel tangents off-axis interaction.

FREQUENCY SIFTERS

Like other acoustic-optic devices, an acoustic-optic frequency sifter (AOFS) Doppler-shifts the frequency of input light by an amount equal to the RF drive frequency, but is optimized specifically for this purpose. Typically our frequency sifters will use the an isotropic interaction of the slow shear mode in tellurium dioxide (TeO₂). Applications such as interference-based optical techniques require a high extinction ratio between the diffracted and diffracted beam. G&H OAFS devices achieve this by using a high-quality optical finish to minimize optical scatter.

We offer standard products with frequency shifts of 40-350 MHz, many of which can be operated in double-pass configurations to double the induced frequency shift. In addition we can design for custom frequency shifts where required. Frequency shifters are fabricated using high quality TeO₂, grown and polished in-house, for lowest insertion loss and excellent power handling. Other acousto-optic materials are available.

The products listed above illustrate a range of typical specifications. Our team routinely works with customers, applying our expertise to customize products to meet the demands of their specific applications.

MULTI-CHANNEL MODULATORS

Independent control of multiple beams or a sheet of collimated light
Acousto-optic multi-channel modulators (AOMC) allow multiple beams to be modulated or deflected independently by integrating an array of transducers with a single acousto-optic crystal. Our proprietary optical and electrical designs minimize crosstalk, allowing concurrent operation of up to 48 channels for modulation and up to eight channels for beam deflection. Our AOMCs are known for their reliable operation and high performance.

Multi-channel modulators have parallel beams as input, each beam independently controlled by a different transducer to modulate its intensity. Multi-channel modulators are most often used for high speed applications like micro machining and direct-write lithography, as each beam can be modulated independently. These devices can also be used to increase throughput when writing large media by writing multiple beams at the same time. Our multi- channel modulators equal the performance available with our single channel modulators, and can be customized for  large aperture applications as well as high speed, small aperture applications.

Multi-channel deflectors
A multi-channel deflector, however, generates multiple diffracted beams from a single input beam at specific locations by simultaneously applying multiple frequencies to a single transducer. Each individual channel is a deflector that can either scan the beam or produce multiple spots. This makes it possible to create a two-dimensional grid. For example, if a four channel deflector were configured so that each channel diffracted three spots, the result would be a 4×3 grid.

CUSTOM M-C MODULATORS
G&H engineers apply their extensive knowledge and experience to design custom products for our customers, to meet their unique needs. If you require a higher number of channels, or another custom parameter, please get in touch with us.

MODULATORS

Single frequency devices allowing intensity modulation of collimated light
Acousto-optic modulators (AOM) allow the intensity of light to be controlled and modulated at rates that far exceed mechanical shutters. AOMs can be used like a shutter (cycling light on and off at a set frequency), or as a variable attenuator (controlling the intensity of transmitted light dynamically). The laser modulation is effected by means of RF induced sound waves creating a periodic refractive-index perturbation in an acoustooptic crystal.

Modulator optimization
The most important factor in selecting a modulator is the required speed. This influences the choice of material, modulator design, and RF driver to be used. The speed of a modulator is described by the rise time, which determines how quickly the modulator can respond to the applied RF driver and limits the modulation rate. Rise time is proportional to the time required for the acoustic wave to traverse the optical beam and for this reason is influenced by the beam diameter within the AOM.

G&H acousto-optic modulators are optimized for low scatter and high laser damage threshold, and can be matched to the rise-time, modulation rate, beam diameter and power handling needs of each application.

Modulator frequency
Modulators fall into two general categories in regards to speed. Very fast modulators can provide frequencies up to 200 MHz and can have a rise time as low as 4 ns. This requires the  input beam to be very tightly focused. Lower frequency modulators do not have this constraint,and can accept larger input beams. Their rise time is usually specified relative to the input beam diameter, in ns/mm.

Modulator extinction ratios
Our modulators typically achieve extinction ratios of >50 dB, usually with a deflected beam throughput of 85-90%. For applications such as intensity leveling where a lower contrast ratio of ~10 dB is acceptable, we offer modulators with >99% light throughput.

APPLICATIONS

• Heterodoxy interferon
• Intensity leveling and modulation
• Laser Doppler velocity and hydrometry (LDV)
• Liar
• Lithography
• Marking, processing, printing, etc.

CUSTOM Q-SWITCHES
The products listed above illustrate a range of typical G&H AOQS specifications. Products can be customized to meet the demands of specific applications.

TUNABLE FILTERS

An acousto-optic tunable filter (AOTF) is a solid-state, electronically- addressable random access optical passband filter. It may be used to rapidly, dynamically select a specific wavelength from a broadband or multi-line source. When specific matching conditions are met, diffraction will occur, making it possible to electronically control key filter parameters, thus providing rapid, dynamic, random access optical filtering. Resolution bandwidths down to <0.1% are available with exceptional performance and with aperture sizes up to 25 mm and beyond. We have developed and patented techniques to allow us to offer options such as large-aperture imaging filtering, side band suppression, and transmission of multiple discrete wavelengths. G&H AOTFs are based on our in-house grown high quality tellurium dioxide, polished and fabricated to rigorous standards. For scanning an entire image in wavelength at speeds sufficient for mealtime video rate spectral imaging, high optical throughput is required. For this purpose devices with large aperture and/or field of view are recommended. When narrow resolution is required and the light source is well acclimated, a “quasi-col linear” AOTF may be more appropriate.

APPLICATIONS

• Con focal microscopy
• Fluorescence & hyper-spectral imaging
• Imaging spectroscopy
• Laser wavelength tuning & selection

RF DRIVERS
For best performance, we recommend a matched RF driver, including the latest digital frequency synthesizer (DFS) driver technology capable of random access wavelength control.

CUSTOM TUNABLE FILTERS
The table above shows a range of typical AOTF product specifications. G&H engineers apply their knowledge to design custom products for our customers, to meet their unique needs. Fiber-coupled AOTF devices are available upon request.

RF DRIVERS

Reliable, versatile electronic control options for acousto-optic devices
An RF driver generates the fixed or variable frequency signal supplied to a device to induce the acousto-optic effect. The frequency and intensity of the signal will determine how much an optical beam is modulated, deflected, or tuned. An acousto-optic device and its RF driver should be paired to optimize speed and stability for each application.

G&H offers a wide variety of dependable high frequency drivers with analog and digital modulation capability, each matched to the device with application- specific features such as first pulse suppression, synchronization, pulse shaping, and multi-channel operation. OEM designs are optimized and streamlined for each customer’s application, maximizing performance in the required cost effective form factor for production at high volume.

Choosing an RF driver
The needs of the AO device dictate the choice of RF driver, including but not limited to:

• RF power: ranges from <0.1 W to >150 W
• Modulation: digital or analog
• Frequency of operation : may be fixed, variable (linearly swept), or programmable
• Stability: influencing choice of VCO vs. DDS when frequency is not fixed
• Number of channels : number of output ports or output tones from a single port
• Special functions : pre-pulse-killing, synchronization, etc.

Modulation: digital vs. analog
The modulation mode determines how the applied RF power is varied, and thus the intensity of diffracted light. In digital modulation, the RF power is applied in an on/off state via an applied TTL signal, thus controlling whether the beam is diffracted or not. In analog modulation, the RF power is controlled through application of a voltage within a specified range, yielding control over the diffraction efficiency and allowing shaping of that waveform in time.

Fixed vs. variable frequency drivers
Fixed frequency drivers provide a single output frequency, controlled via analog or TTL input.
These are used most often for modulation applications. Variable and programmable frequency drivers allow active control of output frequency. Voltage controlled oscillators (VCOs) provide a linearly swept drive frequency, and are flexible enough to be used for any AO device. Direct digital synthesizer (DDS) drivers offer programmable frequency via software. They can create arbitrary waveforms, and thus are ideal for pulse shaping and special functions.

Frequency agility and control
We manufacture DDS drivers that offer high stability and linearity, with fast switching time and high resolution. They are capable of creating arbitrary waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. DDS drivers can be run from a GUI or via driver commands in two modes: 1) random access of specific frequencies, and 2) chirped mode for continuous scanning.

APPLICATIONS

RF drivers play a key role in driving and controlling a diverse range of acoustical devices, including deflectors, cavity dumpers, frequency sifters, mode lockers, modulators (fiber-coupled, free space), multi-channel, pulse pickers, Switches, and unable filters

CUSTOM RF DRIVERS

The products listed illustrate a range of typical G&H AO device driver specifications. Our technical support team is available to advise on selection and optimization of RF drivers for specific applications, as well as customization for OEM integration.

Flexible drivers: The Next Generation

Our unique new 6000 series drivers are designed with additional flexibility to adapt to the varied needs of deflectors, from dual channel to multiplexed, multi-tone, and phased array configurations. This unprecedented level of flexibility in configuration for control of AO deflectors, eliminates the need to design your own drive electronics and simplifying system development.

In addition to single channel operation, these drivers may be configured to control two RF channels independently (dual channel) or together (MUX). The dual channel option allows one driver to control two deflectors in an x-y configuration for 2D scanning with the same frequency, while the MUX configuration uses phase agility for enhanced scanning performance of phased array deflectors. Tunable filters may also be controlled in multi-tone operation. While not limited to this number, G&H has demonstrated 11 simultaneous frequencies facilitating multi-wavelength diffraction. All 6000 series drivers are available in a variety of bandwidths, and with optional water cooled, passive, or active forced air heat sink.
