An RF driver generates a fixed or variable frequency signal supplied to the acousto-optic device&#;s transducer. This in turn uses the piezoelectric effect to very precisely convert the RF signal to an acoustic wave that propagates within the acousto-optic device&#;s crystal. The frequency and intensity of the applied signal will determine how much an optical beam is modulated, deflected, or tuned.
An acousto-optic device and its RF driver should be selected as a unit to optimize speed and stability for each application. Additional driver features include first pulse suppression, synchronization, pulse shaping, and multichannel operation. We offer a wide variety of stable high frequency drivers with analog and digital modulation capability. Voltage controlled oscillators (VCOs) vary the oscillation frequency via the input voltage, and are a costeffective solution for applications with less stringent frequency stability and linearity requirements.
Direct digital synthesizer (DDS) drivers offer higher stability, with fast switching time and high resolution. They can create random waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. They also allow frequency to be varied on the order of a few hundred nanoseconds, and are inherently very linear. DDS drivers are software driven, and can be run from a user-friendly interface (a GUI), or controlled directly via computer driver commands. Our high-performance multi-frequency DDS drivers generate up to 8 channels of RF frequencies simultaneously.
As our AO product lines expand, we are creating more flexible, adaptive RF drivers with dual analog/digital operation and configurable firmware to accommodate functionality like triggering and temperature control without the need for new hardware. Our OEM designs, in contrast, are optimized to each customer&#;s application, maximizing performance in the required form factor.
CHOOSING AN RF DRIVER
The needs of the AO device will dictate the choice of RF driver. The primary factors to consider are shown below, though speed, duty cycle, and special functions are also important.
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. 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 which is matched to the AO device. Offered from 24-440 MHz, fixed frequency drivers may be controlled via analog or TTL input, some with manually adjustable output RF power. These are used most often for modulation applications.
Variable and programmable frequency RF drivers allow active control of output frequency. Voltage controlled oscillators (VCOs) provide a linearly swept (variable) RF drive frequency, and are flexible enough to be used for any AO device. Direct digital synthesizer (DDS) drivers offer programmable frequency. They can create random waveforms from a single, fixed-frequency reference clock, and thus are ideal for pulse shaping and special functions. DDS drivers are software driven, and can be run from a user-friendly interface (a GUI), or controlled directly via computer driver commands. Our high-performance multi-frequency DDS drivers generate up to 8 channels of RF frequencies simultaneously.
DUAL DRIVERS
Dual drivers allow simple or complex digital waveforms to be synthesized, converted to analog signals, and amplified to drive the AO device. This gives great flexibility; for example, it allows the driver to provide multiple programmable frequencies or to swap freely between multiple, complex, bespoke waveforms.
FREQUENCY AGILITY AND CONTROL
We offer Direct Digital Synthesizer (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, with digital words mapping to specific frequencies, and 2) chirped mode for continuous scanning in frequency increments. DDS drivers are also referred to as DFS (digital frequency synthesizer) drivers.
Our technical support team is available to advise on selection and optimization of RF drivers for specific applications, as well as customization of products for OEM integration.

Description of A3 series drivers:
Each Fiber-Q acousto-optic modulator requires an RF driver to control the embedded acousto-optic crystal, as modulation of the beam depends upon the frequency and intensity of the applied RF signal.
The RF signal which generates the acousto-optic wave in the acousto-optic crystal can do so very precisely at a fixed or variable frequency, and is created using a transducer mated to the acousto-optic crystal and driven by the piezoelectric effect.
Analog, digital, and combined RF drivers are available for use with the Fiber-Q series. All are designed for dependable stability and high frequency operation, with compatible options for the full line of visible and NIR Fiber-Q products. The speed and stability of a modulator is limited by the stability and speed of the RF driver, and thus the two should be selected as a paired unit to optimize performance, features, and application-specific options.
The primary factors to consider when selecting an RF driver include the operating frequency, the required rise/fall time of the application, and whether analog or digital modulation is needed. RF power, duty cycle, stability, and variable vs fixed frequency are also relevant.
Drivers for the Fiber-Q series of modulators are designed for constant RF power output, fast modulation, and with conductive cooling via the baseplate. When tuned together with the modulator, they offer stable, dependable modulation to enable all-fiber laser systems.

15 W Output &#; Configurable Operation
Our 15 W output RF driver provides up to two independent RF channels with a fast parallel interface as well as USB controllability.
Ideally suited for controlling a two element phased array acousto-optic (AO) beam deflector (MUX mode), the driver can also be used to drive two single element AO beam deflectors for two dimensional scanning (Dual Channel mode). The driver has additional flexibility for controlling AO tunable filters (multi-tone mode). With its arbitrary waveform playback capability, multiple wavelengths can be simultaneously diffracted by tunable filters and multiple beam spots can be generated by beam deflectors.
Two independent 15 W RF amplifiers are housed in a compact form factor with a fast parallel frequency programming interface. Remote control over an included USB interface is also available with an intuitive command set and GUI. Dual amplitude and relative phase control inputs are included on the rear panel with the parallel interface connectors. Capabilities include dynamic frequency chirp control. An all digital option allows high speed programming of frequency, amplitude and phase. The default, power-on is stand-alone mode, not requiring PC control; connecting the USB connection enables a Host PC mode. A single channel version is also available.
The driver is available in three frequency bands, and each unit includes a monitor output that covers the entire 20-450 MHz frequency band. Driver functionality can be re-configured over the USB interface.

Next Generation AO Modulator Driver
The series RF drivers offer a significant upgrade over our series while maintaining backwards compatibility.
The series RF driver has been a workhorse for powering AO modulator applications over the last decade. The line has received a complete makeover to further enhance the success of this signature driver. All of its functions have been improved and a few key features have been added while maintaining its affordable price.
The modulation input now allows the user to switch from three modulation schemes: Digital, Analog and Digital+Analog. This function will be standard on all models. The RF power has been doubled from 4Watts to 8Watts (at +28Vcc). The features more efficient power consumption than its predecessor. The Frequency range has been increased up to 500MHz, making it able to control any of the currently available AO modulator models. The rise time is <4ns at all power levels and frequencies >250MHz. Another new feature is the optional ability to synchronize the driver to an external clock reference. The RF driver offers more power, higher frequencies, faster rise times, more modulation choices, synchronization capabilities and the latest electronic components over the series driver while maintaining the same footprint and pricing.
