We investigated the acoustic and acousto-optic parameters of cubic crystal KRS-5, which can be used in acousto-optic devices operating with optical radiation from visible to far infrared regions. The results of acoustic and acousto-optic property calculations are presented. Also, we present a possibility of obtaining optical birefringence in cubic material when external static pressure is applied to the KRS-5 crystal.

A tellurium dioxide crystal serves as a prime example of such media, since it possesses record indexes of acoustic anisotropy. We studied one of the unusual scenarios of acoustic incidence and reflection from a free crystal-vacuum boundary in paratellurite.

The reflection process effects on the ultrasound field amplitude and phase structure. The method to simulate the reflected finite ultrasound beam structure in the case of acoustically anisotropic media is presented in this paper.
