Abstract
Results of experiments on the dynamics of scattering in barium titanate are presented. Asymmetric scattering and
centrosymmetric scattering are characterized as a function of incident-beam size, and photographs are presented
showing the development of the beam as light is asymmetrically scattered. Results are compared with existing
theories of photorefractive scattering and are found to be in agreement with a near-forward-scattering theory. We
propose that scattering in barium titanate begins with photorefractive inhomogeneities within the crystal, and
experimental support is presented.
