title: Anisotropy of acousto-optic figure of merit in optically isotropic media.
abstract: We suggest a new approach for analyzing spatial anisotropy of an acousto-optic figure of merit (AOFM). The relations for the effective elasto-optic coefficients and the AOFM are derived for all possible types of acousto-optic (AO) interactions in optically isotropic media, including nonsolid-state and solid-state amorphous media and crystals belonging to the cubic system. Our approach allows for finding the optimal geometries of AO interactions characterized by the highest AOFM for a given material. The analysis is carried out on the examples of cubic KBr and KAl(SO4)2 × 12H2O crystals, which represent different subgroups of the cubic symmetry class.
