We present original data on experiments with cubic photorefractive crystal Bi12TiO20 under
an external dc electric field in the configuration of Z-scan characterization technique. In …

By direct interferometric measurement in Bi12TiO20 under external DC electric field, we
demonstrate that the steady-state photorefractive lens produced by the laser beam with the …

Today beam self-focusing and self-trapping in photorefractive medium is the focus of many
studies, at least as far as steady state is concerned. Photorefractive materials are known to …

The influence of optical activity on two-wave mixing (TWM) in photorefractive BTO and BSO
crystals in the absence of an applied field is studied both theoretically and experimentally …

We report experimental results on the dynamics of formation of a photoinduced lens
produced by a two-dimensional cw He–Ne Gaussian laser beam (633 nm) in a cubic …

A method to characterize the photorefractive parameters of Bi 12 GeO 20 crystal is
described. An analysis of the transient photoinduced grating under an external applied …

We study the polarization properties of volume phase gratings induced in photorefractive
materials that are both optically active and linearly birefringent, such as Bi_12SiO_20 …

The basic physical mechanisms of hologram formation, as well as the major specific features
of Bragg diffraction from anisotropic volume phase holograms recorded in cubic …

Consistent experimental and numerical simulation studies of photorefractive surface wave
propagation in Bi12TiO20 and Bi12SiO20 crystals are presented. We induce the …

We present experimental and theoretical results of photorefractive one-dimensional self-
