摘要：

Quasi-collinear acousto-optic interaction is studied in acoustically and optically anisotropic paratellurite crystals. The possible applications of this interaction in acousto-optic tunable filters with a high spectral resolution are discussed. Different modifications of devices are compared and variants of devices intended for processing tight beams and selection of light signals in fibreoptic communication systems with wavelength division multiplexing (WDM) at lambda similar or equal to 1550 nm are considered.
