Paper Abstract

The numerical investigation uses the intensity-dependent gain coefficient in a coupled-wave formulation which explains nonlinear intensity-dependent behavior associated with the growth of beam-fanning observed in a photorefractive BaTiO3 crystal. The study shows the effect of crystal orientation and biasing illumination on such a nonlinear behavior.
