Abstract

The effect of the spatial dispersion in paratellurite single crystals were studied. It was obtained new effects in the acousto optics of the paratellurite. We explain it in the terms of the Nelson-LAx theory. There are the diffraction of light on a slow transverse sound without polarization reversal and the splitting but not the intersection of the lines of the reverse phase velocities of the fast transverse and longitudinal waves. Also we obtained that the anisotropic diffraction was power then the isotropic one when the light propagated near the optic axis.
