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 …

The transient behavior of the fundamental amplitude of the photorefractive space-charge
field is derived without restrictions within the band transport model. The two-wave mixing …

We present for the first time, to our knowledge, a theoretical analysis of the nonlinear
dynamic space-charge field buildup when a photorefractive medium is exposed …

We present the first complete theoretical model that describes the formation of the space-
charge field in a photorefractive material that is exposed to a sinusoidal ac electric field with …

The space-charge wave theory of photorefractive parametric amplification is presented. It
describes the amplification process in which a strong running holographic grating pumps …

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 …

In this chapter, the standard model accounting for the photorefractive nonlinearity in a
material is presented. The mathematical formalism of the rate equations has been …

Space-charge fields in photorefractive materials enhanced by moving fringes are studied for
simultaneous electron–hole transport. Two distinct models, one with a single set of impurity …

Photorefractive materials have been assuming ever increasing prominence in the non-linear
optics field due to their unique capability for displaying strong non-linear effects at milliwatt …

It is shown that in materials with a special type of photoconductivity temporal response, the
running space charge wave is generated under uniform illumination when the external …
