Holograms recorded under suitable conditions in photorefractive BaTiO 3 exhibit an unusual
dark build-up. The diffraction efficiency increases by some orders of magnitude after the …

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 …

Experimental data on some basic characteristics of holograms recorded in doped and
undoped BTO crystals and fixed at room temperature such as diffraction efficiency and …

We have used the light‐induced grating erasure technique to measure the photorefractive
properties of pure and iron doped BaTiO3. Our experiments were performed using an …

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 …

Photorefractive materials are used for holographic storage, image processing, and phase
conjugation 11, 2/. Especially BaTi03 with its large electrooptic coefficients has been …

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 …

We investigate holographic scattering processes in BaTiO 3 pumped by two coherent
copropagating waves. Four lines are observed on a screen behind the sample. The …

We have experimentally studied the dependence of the diffraction efficiency of nonoblique
transmission holograms in a (110)-cut Bi 12 TiO 20 photorefractive crystal on the orientation …
