Abstract
High-order anisotropic diffraction and anisotropic self-diffraction in barium titanate (BaTiO3), strontium barium niobate (SrxBa1−xNb2O6, or SBN), and barium strontium potassium sodium niobate (Ba2−xSrxK1−y NayNb5O15, or BSKNN) have been observed: up to fourth order in BaTiO3 and SBN and up to fifth order in BSKNN. It is shown that the scattered beams arising from anisotropic self-diffraction are composed of multiple orders. To model anisotropic diffraction, high-order terms have been included in Kukhtarev’s solution of the transport equations for diffusion-dominated transport. Light-induced grating decay rates and diffraction efficiencies were measured as a function of grating vector and modulation index for the first three orders in BaTiO3 and were found to be in good agreement with the model.
