Abstract:

Several novel photorefractive scattering processes were studied. Isotropic scattering of a single intense pump beam was observed and modeled. Numerical calculations, performed using material parameters consistent with the previous experiments, yielded scattering cross sections in excellent agreement with the observations. Anisotropic scattering of a single extraordinary polarized beam into conical rings of light was also observed. Using a phase matching condition and the electrooptic tensor symmetry properties of BaTiO3, the scattering process of the inner ring was uniquely determined. A model which describes the formation of the outer ring was also proposed.
