Acoustic optical modulator driver

direction of the acoustic waves being reversed. 3 AOM Control Within an AOM the acoustic wave is provided by a radio frequency (RF) signal to the AOM, controlled by an AOM driver. This driver is made up of three components, a Voltage Controlled Oscillator (VCO); a Voltage Vari-able Attenuator (VVA); and an ampli er. A schematic diagram of this setup. The Brimrose free space Acousto-Optic Modulator (AOM) is used to control laser beam intensity, frequency modulation, frequency shifting, control pulses, switching time, and more. The AOMs are offered with conduction and water cooled enclosures. TE cooled enclosures are available upon request. • the acoustic frequency, F • the modulation frequency, f mod Note: Your sanity will only remain intact if f mod. piezoelectric •RF driver •power supply (for the RF driver) •function generator (or other Acousto-optic Modulators Author:File Size: KB.

diffracted when the acoustic wave crosses it. • Rise time depends on beam size because a larger beam requires more time for the acoustic wave to cross it. • Example: For 10 MHz modulation, the rise time must be less than 25 ns. If the acoustic wave speed is m/s, this corresponds to a beam diameter of mm. piezoelectric transducer. An acousto-optic modulator (AOM), also called a Bragg cell or an acousto-optic deflector (AOD), uses the acousto-optic effect to diffract and shift the frequency of light using sound waves (usually at radio-frequency). An acousto-optic modulator (AOM) is a device which can be used for controlling the power of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, i.e. the modification of the refractive index of some crystal or glass material by the oscillating mechanical strain of a sound wave (photoelastic effect).
