Free Space Acousto-Optic Modulators

Free Space Acousto-Optic Modulators

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.

Brimrose offers AOMs in the wavelength range from the ultraviolet to LWIR regions for low and high optical power applications. Brimrose AOMs cover the frequency ranges from just a few MHz up to 3.5 GHz.

A large variety of supporting RF electronics in lab enclosures or OEM versions are offered by Brimrose. These include fixed or variable frequency RF Drivers as well as PC-controlled high performance RF Frequency Synthesizers. The RF Drivers are provided with either analog amplitude modulation, TTL, or a combination of both, depending upon application requirements.
