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 …

We investigated both analytically and numerically the simultaneous influence of higher-
harmonic gratings and subharmonic gratings on the threshold for generation of the …

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 …

Nonlinearity of the photorefractive response is studied experimentally and theoretically upon
two-beam interaction of light waves in a bismuth silicate crystal placed in an external …

The space-charge-field harmonics in the refractive-index grating generated in a bismuth
silicate crystal to which a square-wave external electric field is applied were examined …

The photorefractive response in semi-insulating GaAs: Cr is theoretically studied when an
alternating electric field is applied to a crystal. The calculations are based on material …

Проведено экспериментальное и теоретическое исследование нелинейности
фоторефрактивного отклика при двухпучковом взаимодействии световых волн в …

The influence of quadratic recombination is analyzed theoretically and numerically by formal
derivation of the material wave equation including this effect. Analytically, it is shown how …

An analysis is made of photorefractive nonlinearity resulting from the interaction between the
charge gratings formed in a bismuth silicate crystal in an applied meander electric field …
