         New Products             RF Driver
 

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.

Fiber-Q RF Driver
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.
