We develop the nonlinear theory of transversal parametric oscillation in photorefractive
sillenite crystals. The theory is nonlinear in the sense that the nonlinear feedback from the …

The stationary solution is obtained for the photorefractive subharmonic gratings excited in
crystals of the sillenite family by a standing light interference pattern and an applied ac …

A new phenomenon associated with a nonlinear interaction of optically excited space
charge waves has been discovered in photorefractive crystals of the sillenite family. This …

We investigate experimentally and theoretically the dependence of the amplitude of the
spatial fundamental grating, created by a pair of coherent light beams while using the …

When an image is observed through the photorefractive crystal, the multiwave mixing
between components of the image spatial spectrum should lead to drastic image distortion …

We formulate the fundamentals of the nonlinear theory of low-frequency space-charge
waves in semi-insulating photorefractive crystals. This includes an analysis of dispersion …

We have found analytical solutions of the light propagation equations in photorefractive
materials with strong optical activity and absorption. These solutions show the occurrence of …

We present a theory of resonant photorefractive wave coupling in cubic photorefractive
crystals that are in general optically active. This theory includes the resonance enhancement …

A simple theory based on Kukhtarev's materials equations and linear stability analysis is
developed providing the threshold conditions for the spontaneous emergence of spatial …
