Abstract
Thermally induced beam distortions in laser ceramics with arbitrary grain size have been investigated. A model for the spatial spectral density of dielectric permeability variations was suggested. The average scattered intensity was calculated using the small disturbances method (theory of Rayleigh–Debye scattering). The direction pattern of the scattered field and the extinction coefficient have been obtained. The scattered power and the depolarization ratio fit with the corresponding values obtained in the geometric optics approximation in the range of its validity.
