Beam fanning in low-symmetry photorefractive crystals features nonuniform angular distribution of linear polarization. We study this phenomenon experimentally in monoclinic Sn2P2S6 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.
