Abstract
The theory of Bragg acoustooptic interaction of multi- component optical radiation with a single acoustic wave is developed. The multi-component radiation is assumed to be a multi frequency beam with two possible polarizations of each component. It is shown that the deciding factor for such interaction is to establish the phase synchronism conditions between every component of the optical radiation and the acoustic wave. This diffraction can be realized in anisotropic media only. These ideas are experimentally confirmed by using a two-color optical radiation diffracted on a single acoustic wave propagating in TeO2 mono crystal. Two diffraction regimes of six-component Ar-laser radiation are proposed and investigated. A total diffraction efficiency up to 90% is obtained.
