Several techniques have been developed for improving the performance of acousto-optic Bragg cells. These techniques include, birefringent phase matching, planar acoustic beam steering, the combination of the two, and optical multiple pass. The principles of these techniques and the enhanced performance, including increasing bandwidth and efficiency will be described.
