Brimrose is a world technology leader in the area of Acousto-Optic components, serving the U.S government and world wide industry since 1979. This experience is carried through today's product lines, including: Acousto-Optic Tunable Filters (AOTFs), Acousto Optic Modulators,
Acousto Optic Frequency Shifters, Acousto Optic Mode Lockers, Acousto Optic Deflectors (Click PLoS ONE Research Article to see Brimrose 2D AO Deflector application),
Acousto Optic Cavity Dumpers, Acousto Optic Q-Switches, and fiber optically pigtailed devices. 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. For more information, please contact at ao@brimrose.com.
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.
