Polarization structure of beam fanning in low-symmetry photorefractive crystals

Abstract

Beam fanning in low-symmetry photorefractive crystals features nonuniform angular distribution of linear polarization. We study this phenomenon experimentally in monoclinic ${\mathrm{Sn}}_2{\mathrm{P}}_2{\mathrm{S}}_6$ crystals that belong to the $m$ class of symmetry and compare the results with the predictions of a simple model that describes amplification of a weak scattered wave via nonlinear coupling to the intense incident wave.
