摘要：

Light-induced holographic scattering is investigated in photorefractive Sr0.61Ba0.39Nb2O6 (SBN) crystals, in which diffusion charge transport dominates. A crystal is illuminated with two coherent pump beams and different scattering patterns are observed on a screen behind the crystal. We attribute the patterns to certain phase-matching conditions, which allows the identification of the parametric processes that are involved.
