Abstract

Nonmechanical methods for effecting deflection and translation of laser beams without frequency shifting are described. For beam deflection two Bragg cells having different acoustic velocities are used. For pure beam translation, a single Bragg cell through which the beam travels twice may be used. Detailed acoustooptical analyses for these devices are included as well as discussion of an application for an optical heterodyne radio-frequency tunable receiver.
