Abstract

We have observed in experiment the effect of strong dispersion of thermally induced depolarization in ceramics, which we earlier predicted theoretically. This effect is specific to ceramics only and has no analogs either in glasses or in single crystals. The consequence of this effect is that both the polarized and depolarized radiations always have a small-scale intensity modulation with a characteristic transverse size of the order of a grain size. Depth of this modulation increases with increasing heat release power and decreasing ratio of sample length to grain length.
