Abstract
Image amplification and beam fanning in a photorefractive medium are d escribed by the multivariable Langevin equations when the random volum e scattering is included owing to the inhomogeneities and/or defects d istributed throughout the medium. The effects of the random volume sca ttering on the image amplification and the beam fanning are studied an alytically in the undepleted-pump approximation and numerically, and t hey are compared with the surface scattering.
