Annotation
The results are presented of theoretical studies into the diffraction of light by an amplitude-modulated acoustic wave in conditions of strong acoustooptic interaction. The diffraction efficiency is calculated for a Bragg-type modulator. It is demonstrated that where the modulation frequency is high enough, the symmetry of the acoustooptic coupling is disturbed so that the diffraction efficiency may be as high as 94% even for a focused light beam.
