The recent study of nonlinear optical properties of photorefractive materials has led to the
experimental observation of anisotropic energy transfer in two-wave mixing, l the …

A theoretical analysis is presented of two-wave mixing in photorefractive materials in which
the complex amplitude of a weak signal beam has slowly varying but otherwise arbitrary …

The effect of a position-dependent time constant on nondegenerate photorefractive two-
wave mixing is analyzed. For codirectional two-wave mixing the results indicate that the …

Self-focusing and self-defocusing of light in two-wave mixing are investigated
experimentally. Amplification and self-focusing are measured as functions of the frequency …

We investigate the dynamics of multiple two-wave mixing in photorefractive materials. This is
the first time to our knowledge that a study of the dynamics of many pairs of two-wave mixing …

We propose and demonstrate a new method to measure the two-wave mixing coefficient
with slight influence of beam fanning in thick crystals with high coupling constants. The …

A theoretical and experimental study of photorefractive nonlinear multi two-wave mixing is
given. It is used to describe the fanning effect, which is an asymmetric self induced light …

A recently predicted resonant effect for the enhancement of two-wave mixing in
photorefractive materials is investigated. The resonance occurs when the frequency of the …
