Theoretical and experimental investigations of the linear and nonlinear space–charge field
effects in photorefractive materials are reviewed. In particular, the aim is to explore the …

Polarization hologram recording based on the effect of photoinduced anisotropy (PA) is
reviewed, focusing on amorphous chalcogenides (ACh). Possible PA mechanisms in ACh …

We assess the influence of the non-uniformity of a recorded grating on the prediction of the
diffraction efficiency taking into account optical activity, absorption of light, birefringence …

The introduction of certain electronic feedback loops into photorefractive wave-coupling
schemes makes them noise free and leads to dramatic changes of the whole nonlinear …

Взаимодействие световых волн на отражательных фоторефрактивных решетках

Simple formulae for the two-wave mixing (TWM) gain and diffraction efficiency obtained in
the approximation of weak coupling and strong optical activity allow us to tune the …

On the basis of the vectorial theory of light diffraction in cubic photorefractive crystals, we
derive analytical expressions to describe the output intensities and polarization states of two …

This chapter provides the first systematic description of the basic properties of low-frequency
space-charge waves (SCWs) in photorefractive materials, and the effects caused by these …

We show that a hybridization of the optical and material nonlinearities takes place near the
threshold of the subharmonic generation in photorefractive crystals. It results in a critical …
