Abstract

Theoretical model of non-stationary process of self- amplification of weak holographic gratings in birefringence photorefractive crystals is submitted at two and one- frequency reading in view of multiwave and vector character of interactions. The analytical solutions of interconnected equations of record and diffraction are found. The effects of the spatial-time transformation of the grating and nonuniformity of the gain and also the dynamics of polarization and selective properties has been studied using numerical simulations at inter-mode and within-mode interaction geometries in optically active cubic crystals.
