title: Prediction of the physical response for the two-photon photorefractive effect.
abstract: We present a new model for the two-photon photorefractive recording process. We solved the resulting set of nonlinear coupled partial differential equations of the model within a linear approximation of the steady state. We found very good agreement with experimental results.
