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 holographic recording on photorefractive Bi 2 TeO 5 crystals using λ= 633
nm wavelength light. We studied the behavior of this material under the action of this low …

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 …

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 report the recording of optical gratings on photorefractive \rmBi_2\rmTeO_5 Bi_2TeO_5
crystals using λ=532\,\rmnm λ= 532nm wavelength light. We studied the behavior of this …

Bismuth tellurite has a unique feature, a long-living (years) photorefractive memory that
develops in the four-wave mixing process without fixing. Single crystals of Bi2TeO5 were …

Bismuth tellurite-Bi 2 TeO 5 is a new photorefractive material recently available for optical
memory investigations. Analogue volume holograms of a two-dimensional test pattern were …

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 …

Bismuth tellurite (Bi2TeO5) is a new photorefractive material that is now available as single
crystals of high optical quality. The results of measuring the photorefractive properties of …

Abstract Bismuth tellurium oxide (Bi 2 TeO 5) is a new material expected to exhibit nonlinear
properties because of its noncentrosymmetric crystal structure. A conventional crossed cw …
