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 …

Abstract Photorefractive Bi12TiO20 single crystals of high optical quality were grown in a
resistive heating furnace from high temperature nonstoichiometric (10: 1) solutions of Bi2O3 …

Bi12TiO20 (BTO) single crystals nominally pure and doped with ruthenium are grown by top-
seeded solution growth method. The effect of ruthenium concentration on optical and …

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 …

We report on the presence of a strong photovoltaic effect on nominally undoped
photorefractive Bi 2 TeO 5 crystals and estimated their Glass photovoltaic constant and …

We report on the light-induced absorption in undoped photorefractive Bi_2TeO_5 (BTeO)
crystal. The so-called “two-center” model is shown to adequately describe the present …

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 …

Analysis of two-wave coupling in cubic crystal classes 23 and 4¯ 3m is presented for
arbitrary orientation of the grating vector and the applied electric field. We show that the most …

The influence of the anisotropy of the effective dielectric constant, effective electro-optic
effect, drift mobility, and photoexcitation cross section on the photorefractive two-wave …
