The Raman-Nath, intermediate and Bragg regimes of acousto-optic interaction in an acoustically anisotropic medium are theoretically examined in the paper. The general model of the interaction is extended over the case of an elastically anisotropic medium. Basic results of computer modeling of diffraction processes taking place in crystals are presented in the paper. The interaction of light and ultrasound is investigated in media with arbitrary elastic anisotropy in a wide range of the Klein-Cook and Raman-Nath parameters. The influence of the acoustic anisotropy on the process of light diffraction, especially on the light intensity in diffraction maxima, is also discussed.
本文理论研究了各向异性介质中声光相互作用的喇曼-纳斯、中间和布拉格区域。本文将一般的相互作用模型扩展到弹性各向异性介质的情况。本文还给出了晶体中发生的衍射过程的计算机建模的基本结果。在较宽的 Klein-Cook 和 Raman-Nath 参数范围内，研究了各向异性介质中光和超声波的相互作用。还讨论了声波各向异性对光衍射过程的影响，特别是对衍射极大处光强度的影响。
