High-efficiency multibeam acousto-optic diffraction of pulsed light with nonequidistant beams

Acousto-optic diffraction of pulsed laser radiation on a multifrequency acoustic wave has been studied. It is established that the high efficiency of diffraction (i.e., the formation of a multibeam optical field with low losses) can be also achieved for a nonequidistant set of frequencies and, hence, nonuniform distribution of beams in the angular space. Results of experimental verification of the proposed approach are presented.
