This chapter is an overview of the photorefractive effect, the important photorefractive
nonlinear processes and common photorefractive materials. In Section 2, the formation of …

The steady-state solutions for higher harmonic gratings that describe the space-charge field
in photorefractive materials are derived without restrictions within the shallow trap model …

El conocimiento del régimen no lineal, donde se generan las redes fotorrefractivas
armónicas está prácticamente limitado a un conocimiento aproximado del modelo de …

In our work we propose a novel method of analysis of photorefractive transport equations.
The method based on a perturbative approach can be used in the case of two wave mixing …

Adaptive RF interference reduction for broadband communication systems continues to be
problematic. The acousto-optic RF signal excision system offers real-time, narrowband RF …

The steady-state analytical expressions for the space-charge field harmonics generated by
the high contrast interference pattern in biased photorefractive material with ambipolar …

The high-modulated phase gratings induced in photorefractive crystals are anharmonic. For
small angles between incident beams (thin grating regime), an additional mixing can appear …

Light-induced charge gratings on photorefractive materials are investigated using
electrostatic force detection with an atomic force microscope. The high sensitivity of the …

We have observed multiple-order diffraction from photorefractive gratings formed by two
input beams of comparable intensity that interfere in a single crystal of SBN: Ce. High-order …

The saturation of the fundamental harmonic of the space-charge field is investigated
experimentally in dependence of the contrast m and the amplitude of an external ac and dc …
