Аннотация:The Bragg diffraction of light from a sinusoidal phase grating induced in an anisotropic medium by an acoustic wave has been studied theoretically for the case of a large acoustic energy walkoff. Based on
the modified coupledwave equations, the frequency and angular characteristics of an anisotropic diffraction
in a paratellurite crystal have been calculated. It is shown that the acoustic beam walkoff significantly
changes the angular and frequency ranges of acoustooptic interactions.
