This is the final report for a 21 month study investigating the use of acoustic-optic beam steering for inter-satellite laser communications lasercom. The basic technique is demonstrated in a breadboard that uses a customized 2-dimensional acoustic-optic Bragg cell deflector and a magnifying optical system comprised entirely of off-the-shelf components. The breadboard was designed to steer a laser over a range of 360 x 36 degrees. Important characteristics of the acoustic-optic Bragg deflector include high angular resolution, fast switching speed, high electrical and optical efficiency, and high reliability with no moving parts.
