Abstract

The quasi collinear acoustooptical interaction in which the energy propagation directions of optical and acoustic beams coincide is theoretically investigated. In this case the wave vectors of the acoustic and optical waves perform a closed triangle. The system of two first order equations is deducted that bound amplitudes of transmitted and diffracted light beams and of acoustic beam. This beam is propagating in a media with an acoustic energy walk-off. Simultaneously an acoustic beam anisotropic distortion is considered. The solution of these equations with an appropriate boundary conditions was carried out in the case of strong acoustooptical interaction. Some particular cases of a quasi collinear interaction were analyzed at the different levels of an input acoustic energy density.
