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 …

BaTiO_3 single crystals were grown by the top-seeded solution growth technique in inert
atmospheres of nitrogen gas and of argon gas and in air. They were then annealed at 1200° …

Photorefractive (PR) gratings have been induced by 442-nm light illumination in
Bi_4Ge_3O_12 single crystals doped with Cr impurities. In undoped material no grating was …

12 TiO 20. The first two can be measured by simple and classical methods, but the
coexistence of optical activity, electrogyration, field-induced linear birefringence, and …

We demonstrate the extension of the photorefractive effect in BaTiO_3 crystals to the 1.5-μm
wavelength regime, which is obtained by two-photon absorption induced by intense …

We investigate the absorption and photorefractive properties of Ce: BaTiO3 (cerium doped
barium titanate) crystals. The absorption coefficient, electro-optic gain coefficient, and total …

We have measured the anisotropy of the mobility of photo-excited holes in nominally
undoped single-crystal, poled, ferroelectric BaTiO 3 (p-BaTiO 3) at room temperature. In this …

It is shown experimentally that the nonsymmetric behavior of the beam-coupling gain
coefficient of BaTiO_3 crystals with respect to the sense of the c axis is caused by an …

Photorefractive two-beam coupling and energy transfer in BaTiO3 are studied at multiple
wavelengths using He-Cd, He-Ne, and diode lasers. The photorefractive signal beam gain is …

Optical absorption measurements in the visible and infrared and reflectivity measurements
in the visible and ultraviolet are reported for single crystals of bismuth tellurium oxide (Bi 2 …
