This paper discusses frequency-degenerate vector four-wave mixing of light at reflective
photorefractive gratings in cubic gyrotropic crystals. Coupled-wave equations are obtained …

The conditions of high gain in wave mixing experiments with moving gratings in
photorefractive BSO crystals are reviewed. It is shown that under optimum recording …

In wave mixing experiments with photorefractive crystals such as Bi 12 (Si; Ge; Ti) O 20 the
efficiency of the interaction is greatly improved when recording with a moving grating: nearly …

We study the simultaneous influence of optical activity, piezoelectric effect, and elasto-optic
effect on two-wave mixing (TWM) under diffusion recording in photorefractive Bi_12TiO_20 …

Abstract Lasing at the He-Ne wavelength (633 nm) in a ring oscillator geometry has been
demonstrated experimentally using a cubic photorefractive Bi12TiO20 crystal in an external …

Large values of the exponential gain coefficient Γがんま are obtained (Γがんま≂ 8–12 cm− 1) when
recording with a moving grating in photorefractive BSO crystals (nearly degenerate two …

Simple analytical expressions for the dependence of the maximum gain on the polarization
angle of the interacting light waves and the crystal thickness are obtained for two-wave …

The polarization structure of the signal wave that interacts with a circularly polarized pump

Due to the co-existence of optical activity and linear birefringence in a Bi 12 SiO 20 crystal, a
phase gratting induced in this medium has many interesting and unusual properties. We …
