We report on a scheme to improve the pointing stability of the first order beam diffracted by an acousto-optic modulator (AOM). Due to thermal effects inside the crystal, the angular position of the beam can change by as much as 1 mrad when the radio-frequency power in the AOM is reduced to decrease the first order beam intensity. Highly available RF Drivers for acousto-optic modulators; Linear RF power for imaging and engraving. 20 years of development, always in close cooperation with our customers, has created a large number of innovative devices for the acoustic-optical field. Reliability, temperature stability, functionality and compact dimensions were the major. AOM has the drivers included, that means the price is for whole unit,an Acousto optic modulator and a driver. An acousto-optic modulator (AOM) 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). 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. Considering the more subtle aspects of each customer’s specific application, we work to identify the ideal device and RF driver. Innovative acousto-optic device designs stretch minimize undesirable effects of crosstalk, light leakage, and beam distortion.
