We report the optical absorption and photorefractive properties of a series of cerium‐doped
barium titanate crystals. The light‐induced absorption and the intensity‐dependent two …

Suppression of an optical carrier from an RF modulated laser beam of wavelength 532 nm is
performed using two-beam coupling in photorefractive barium titanate. A theoretical analysis …

From correlated SIMS and EPR studies on high resistive, vanadium doped CdTe and
ZnCdTe bulk crystals we have determined the total V concentration [V] and the [V3+] and …

Two-wave mixing of phase-modulated beams in photorefractive crystals under a dc electric
field is studied both theoretically and experimentally. Based on the vectorial theory of light …

The time-resolved photoelectric spectroscopy technique was used for the characterization of
semi-insulating CdTe: V crystals using a short light pulse with 9 ns duration from a nitrogen …

We report measurements of response time for the intensity-dependent absorption in a single
BaTiO_3 crystal under conditions in which no photorefractive effect can be observed. The …

We demonstrate that the photorefractive effect in GaP crystal at 633 nm can be enhanced
using an externally applied dc field and a moving grating. A two-beam coupling gain …

An expression for the gain in photorefractive two-wave mixing when radio-frequency (rf)
electric fields are applied to the material has been derived and compared with experiments …

Two optical beams can couple in a photorefractive crystal without using the electro-optic
effect. Beam coupling is due to a spatially modulated absorption caused by the …
