A summary is given of techniques and results for calculating light scattering in anisotropic crystals valid for arbitrary directions of the incident beam, the scatter beam and the crystal surface normal relative to the crystal axes. A dyadic Greens function that distinguishes ray and propagation directions leads to a scattering efficiency inside the crystal that involves the Gaussian curvature of the surface of wave normals. After taking account of the solid angle expansion, and the source volume demagnification at the crystal surface a scattering formula is given suitable for comparison with the experiments done outside the crystal. Application is made to Brillouin and Raman scattering. Author
