摘要：
The anisotropy of the acousto-optic (AO) figure of merit for the case of anisotropic AO diffraction has been analyzed for Tl3AsS4 crystals in the principle crystallographic planes. It has been found that the most effective geometries of anisotropic AO Bragg diffraction belong to those that concern interaction with the slowest acoustic wave, i.e., in the ab plane with M2=2020x10-15 s3/kg and the ca plane with M2=1940x10-15 s3/kg. The efficiency of the collinear AO diffraction is highest in the ca plane (M2=141x10-15 s3/kg).
