title: Numerical analysis of vectorial two-beam coupling in photorefractive materials.
abstract: A numerical model is presented for the analysis of vectorial twobeam coupling in photorefractive materials. A powerful software tool has been developed for design purposes. For Fe,Ce-doped lithium niobate crystals, conversion efficiency and signal gain dependences on experimental parameters and beam polarization have been found. The good accuracy of the model has been demonstrated by comparisons with experimentally measured parameters.
