Abstract :
Interaction of acoustic and light waves with accounting for elastooptic and elastogyration effects is theoretically described. Collinear acoustogyration diffraction in quartz and paratellurite crystals is experimentally investigated and thoroughly analysed. Piezogyration effect is experimentally studied for TeO2 crystals. The acoustogyration efficiency and the acoustogyration figure of merit calculated for a number of crystals (GaAs, TeO2 and SiO2) are shown to be too small for experimental detection. On the other side, we demonstrate that the effect of light diffraction on periodical distribution of the imaginary part of dielectric permittivity perturbed through the piezogyration effect can be observed for the case of interaction of optical wave with enantiomorphous ferroelastic domain structure.
