We investigate the dynamics of beam fanning in a photorefractive barium titanate crystal at
different wavelengths and with a mixed-polarization state of the input beam. The …

Self-defocusing of a Gaussian light beam in a bulk photorefractive BaTiGl crystal is
demonstrated. This is a low light intensity process which results from the coupling and power …

The possibility of phase conjugate mirrors (PCM's) with reflectivities exceeding unity was
predicted by Yariv and Pepper, I and subsequently observed by Bloom, Liao, and …

Recent analytical results in the frame of photorefractive spatial-soliton propagation are
exploited to derive a novel scheme for the investigation of space-charge field formation in …

We analytically solve charge-transport equations for a photorefractive crystal with shallow
and deep traps. We predict that, if shallow traps can accumulate a high density of charge …

For the first time to our knowledge, photorefractive properties have been observed in planar
waveguides fabricated by the technique of ion-beam implantation in BaTiO_3 single …

We present the theoretical and experimental results of photorefractive two-beam coupling in
Cr-doped strontium barium niobate: 60, using thermal excitation (ie, dark conductivity) to …

Two new types of parametric scattering of light in photorefractive BaTiO, crystals are
investigated. Nonlinear scattering requires two orthogonally polarized pump beams. It is …
