Bi 2 TeO 5 is a new nonlinear optical material that exhibits the photorefractive effect
including a long lived memory component. The nonlinear absorption properties of the …

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 …

Refractive index gratings were written by 18 ps laser pulses in a new photorefractive
material Bi 2 TeO 5. The time evolutions of the gratings were followed by delayed probe …

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 …

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 …

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 tellurite (Bi2Te05) is a new nonlinear optical material which has only
recently been prepared in single crystal form suitable for optical investigations. The material …

Single crystals of Bi, TeO,, both undoped and doped with transition-metal-ion dopants, were
grown with high optical quality. Continuous-wave four-wave-mixing experiments on these …

BaTiO3 and BaTiO3: Ce thin films with good surface morphology and tetragonal perovskite
structure were fabricated on quartz substrates by pulsed-laser deposition technique at a …

Spectral dependences of optical absorption coefficient of the bismuth tellurite single crystals
grown by Chohralsky method have been observed. The investigations were carried out on …
