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 …

The analytic expressions for the first three higher-order harmonics of the space-charge field
versus time are obtained by use of the hopping model of Feinberg [J. Appl. Phys. 51, 1297 …

This chapter provides a detailed review of theoretical work on the photorefractive effect. The
physical model of photorefractivity used here, which now seems well established by many …

Equations for the grating space-charge density and concentration of free carriers induced by
a standing light wave in an anisotropic photorefractive crystal are derived and solved. The …

Solutions to the band-transport equations are developed to include effects on the amplitude,
dynamics, and spatial-frequency response of the space-charge field when periodic or dc …

It is shown that the spatial variations of physical quantities like space charge electric field,
ionized donor density modulation and electron density modulation may be characterized by …

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 …

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 …
