title: Photorefractive shooting stars.
abstract: Under certain conditions the direction of a beam diffracted from a photorefractive grating wanders as the grating decays. This phenomenon is due to competition between the original grating and those formed spontaneously by the Fabry-Perot modes produced by the crystal's surfaces.
