Results of the theoretical investigation of light nonreciprocity relationships between the amplitude and phase of diffracted light waves in the collinear Acousto – optic interaction through high frequency are presented. It is shown that the nonrecipricity of the amplitude and phase of diffracted waves are a more complicated nature than Bragg regime. An additional phase shift resulting from the violation of the phase-matching condition of the interaction waves leads to difference in Bragg angle for waves propagating in opposite directions. The magnitude of the effect can be controlled by varying power or frequency of the ultrasound, length and geometrical the interaction. The studied feature of acousto-optic interaction must be taken into account in design of modern Acousto-optical devices, particularly those using optical heterodyning, Electro-Optic field especially Q-switching.
