Photorefractive materials combine photoconductive and electro-optic properties: light affects
their electrical conductivity; their optical properties (refractive index, etc.) are affected by …

Photorefractive Materials presents an overview of the basic features and properties of
photorefractive materials, covering a wide array of related topics. It provides a coherent …

We demonstrate the extension of the photorefractive effect in BaTiO_3 crystals to the 1.5-μm
wavelength regime, which is obtained by two-photon absorption induced by intense …

We derive an analytical expression describing the effect of phase modulation in two-wave
mixing for dynamically recorded phase-shifted holograms in photorefractive materials. The …

The buildup and the decay of photorefractive two-beam coupling are experimentally
demonstrated to be strongly dependent on the intensity ratio of the two beams (signal-to …

We show that absorbing photorefractive materials characterized by a space-charge
exponential relaxation time law exhibit an overall hologram optical erasure that is described …

We utilize the finite time constant of a photorefractive optical novelty filter microscope to
access full-field velocity information of fluid flows on microscopic scales. In contrast to …

Equations that describe the steady-state dependence of the coherent-coupling properties of
photorefractively induced refractive-index gratings on high-speed periodic biphase …

Unexpectedly fast response (35 ms) of beam fanning has been measured in a fiber-like
photorefractive sample of Bi/sub 12/TiO/sub 20/(BTO) crystal. Nonlinear interaction between …

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 …
