Estimating the Parameters of Monocrystal-Based Acousto-Optic Devices for Terahertz Radiation Control

The acoustic and optical properties of a number of monocrystals transparent in the terahertz range are systematized. Acousto-optic (AO) figure of merit is calculated for the quasi-orthogonal and collinear geometries of AO interaction. The parameters of AO deflectors and filters of THz radiation are determined.
