Barium titanate (BaTiO3) was one of the first ferroelectric materials to be discovered, and
also one of the first to be recognized as photorefractive [7.1]. The particular advantage of …

We have used a number of experimental techniques to identify the photorefractive species in
commercial samples of BaTiO_3. We find that Fe impurities (in the Fe^ 2+ and Fe^ 3+ states) …

Single crystals of Bi12TiO20 (BTO) are grown by a modified Czochralski technique. Doping
with cadmium, calcium, gallium, and vanadium is performed by adding corresponding …

We present data on the speed of light‐induced refractive index changes in a BaTiO3 single
crystal. The light‐induced erasure rate of a refractive index grating is shown to depend on …

BaTiO 3 was one of the first ferroelectric materials to be discovered, and also one of the first
to be recognized as photorefractive [1]. The particular advantage of BaTiO 3 for …

We report the presence of quasipermanent effects of photochromic and hole-photorefractive
nature in Bi 12 TiO 20 (BTO) at low irradiance at 514.5 nm. A new selective two-wave mixing …

A complementary photorefractive grating was created and stored in BaTiO_3. For a grating
wave vector oriented along the crystal's c axis, the grating first appeared above 80° C and …

The possibility of using the cubic photorefractive crystal Bi12TiO20 (BTO) in a real-time
holographic interferometer has been demonstrated. This crystal has a half-wave voltage of …

Beam-coupling experiments are carried out with two BaTiO_3 crystals as a function of the
intensity and wavelength. We demonstrate in these experiments that hole–electron …

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 …
