We present a detailed theoretical analysis of the properties and formation of single solitons
and higher-order bound dipole pairs in media with anisotropic nonlocal photorefractive …

We investigate experimentally the fundamental characteristics of space-charge waves
excited in a photorefractive crystal of Bi_12SiO_20. Features such as their transient rise and …

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 …

We found that the formation of self-pumped phase-conjugate mirrors SPPCM in
photorefractive Bi12TiO20 crystals under external alternating electric field is accompanied …

We investigate theoretically and experimentally the operation of a nonlinear system,
feedback controlled photorefractive beam coupling. It is shown that the feedback equations …

We investigate the physics of a novel nonlinear system, feedback controlled photorefractive
beam coupling. Inertia of the electronic feedback is found to be an element crucial for …

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 …

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 …

A Nd: Bi12SiO20 crystal was grown by the Czochralski method. The thermal properties of
the crystal were systematically studied. The thermal expansion coefficient was measured to …

This paper consists of two parts. The first contains a short review of the main characteristics
and holographic phenomena typical of sillenites, and the second part is devoted to new …
