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 …

The detection of small-amplitude ultrasonic vibrations is very important for applications in
such fields as nondestructive testing, quality control, and condition monitoring. The surface …

We present exact analytical bright and dark (black and grey) solitary wave solutions of a
nonlinear Schrödinger-type equation describing the propagation of spatial beams in media …

A novel analytical description of the nonlocal anisotropic space charge field, induced by (2+
1) D localized light beams in photorefractive crystals, is introduced. Closed-form expressions …

We investigate light beam propagation in a fast photorefractive medium placed in an
alternating electric ac field to enhance the nonlinear response. It is shown that the joint …

An analysis of light-induced space-charge field, valid for the propagation of two-dimensional
solitons in photorefractive (PR) crystals, is carried out. Under conditions appropriate to 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 develop the theory of vectorial beam coupling in cubic photorefractive crystals to
describe the effect of fast phase modulation on output intensities and polarizations. Special …

A frequency-degenerate steady-state two-wave interaction on a dynamic transmitting phase
grating formed in a cubic crystal of the ̄ 43m symmetry group with a nonlocal …
