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.
