Acousto Optics

Brimrose is a world technology leader in the area of Acousto Optics. Product lines include Acousto-Optic Tunable Filters (AOTFs), Acousto Optic Modulators, Acousto Optic Frequency Shifters, Acousto Optic Mode Lockers, Acousto Optic Deflectors, Acousto Optic Cavity Dumpers and Acousto Optic Q-Switches. Driving electronics are also available for all devices.

Acousto-Optic devices are used in laser equipment for electronic control of the intensity and position of the laser beam. Acousto-optic interaction occurs in all optical mediums when an acoustic wave and a laser beam are present in the medium. When an acoustic wave is launched into the optical medium, it generates a refractive index wave that behaves like a sinusoidal grating. An incident laser beam passing through this granting will diffract the laser beam into several orders. With appropriate design, the first order beam has the highest efficiency. Its angular position is linearly proportional to the acoustic frequency, so that the higher the frequency, the larger the diffracted angle.

Brimrose AOTF technology has been recognized throughout the world for the past 40 years. Our Acousto-Optic devices have been on the International Space Station and our AOTF-NIR spectrometers are now on their way to the moon to help NASA’s search for water.
