Acousto-optic interaction of two-color beam in isotropy media

Bragg acousto-optic interaction in isotropy media is considered. The basic idea of this diffraction is grounded on the splitting the incident two-color light into two separate beams due to Snell's law and the fitting the Bragg synchronism for every beam and a single acoustic wave. Two variants of such diffraction are possible: diffracted beams propagate at one side respect to the incident beam, and they propagate at opposite sides respect to incident one. We have shown that the first variant is preferable for applications because of better fulfilling of Bragg diffraction conditions.
