The photorefractive coupling of two polarized electromagnetic waves in cubic crystals is
considered. Exact solutions for the cross-polarization coupling are obtained. Both …

In LiNbO_3: Cu and LiTaO_3: Cu crystals, simultaneous anisotropic scattering has been
observed in two conical rings: one corresponding to a scalar noisy grating recording with …

A self-pumped phase conjugate reflection induced by another mutually coherent incident
beam has been observed and explained successfully for the first time in a photorefractive …

We have measured the anisotropy of the mobility of photo-excited holes in nominally
undoped single-crystal, poled, ferroelectric BaTiO 3 (p-BaTiO 3) at room temperature. In this …

We describe a novel accurate method to measure energy transfer between two beams
coupling in photorefractive materials. We have used this method to measure the on-line …

Asymmetric and centrosymmetric scattering are investigated in barium titanate. The
dependence of scattered intensity on beam diameter is experimentally derived and shown to …

We present experimental data for BaTiO_3 that exhibit an intensity dependence in the
absorption coefficient and the two-beam coupling coefficient at intensities between 0.002 …

Photorefractive simple and double phase-conjugate mirrors very often exhibit strong
instabilities in their reflectivities. One of their possible origins can be the competition …

We demonstrate optical-beam phase conjugation by the process of two-beam coupling in
photorefractive barium titanate. The incident, image-bearing beam causes exponential gain …

In signal beam amplification by two-beam coupling in BaTiO 3 photorefractive crystals, beam
fanning in the direction of the amplified signal reduces the signal-to-noise ratio (SNR). The …
