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 …

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 …

A laser beam incident on BaTiO 3 can cause a cone of light to exit the crystal. If the incident
beam is polarized as an extraordinary ray, the cone of light is formed by ordinary rays. The …

Large nonlinear changes of the refractive indices in photorefractive crystals cause various
light-induced scattering processes [1 to 71. In principle all nonlinear scattering nearly …

The photorefractive properties of Bi2TeO5 crystals were measured with the wave mixing
technique using the 532 nm output of a Nd: YAG laser for writing gratings. The saturation …

Abstract A photorefractive Bi 12 TiO 20 (BTO) crystal is exposed with high intensity pulsed-
laser beams 532 nm (the average intensity of the laser was 110 mW/cm 2, the average …

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 …

In this letter, we present the results of two-wave mixing experiments performed with several
BaTiO:> crystals in the temperature range between 20 and 125" C. Earlier publications by …

Abstract The photorefractive crystal, Bi 2 TeO 5, was grown by the modified Bridgman
method for the first time. High purity Bi 2 O 3 and TeO 2 were used as starting materials and …
