title: Laser beamsteering using the photorefractive effect.
abstract: A new configuration for laser beamsteering based on the photorefractive effect is presented. This method has the potential to produce several thousand beam positions, with a random access time of <1 msec. The method has a theoretical efficiency approaching 100%. The principles of device operation are presented, including a writing beam geometry which will allow the efficiency to be maintained over a wide field of view. A scheme for generating the required writing beams and results of a proof-of-concept experiment are presented.
