Two coherent light beams can couple in any absorbing material owing to a light-induced
modulation of the material's dielectric constant. In photorefractive crystals the coupling …

An alternative empirical correction function is presented for the space-charge field of the
form ƒ (m)= m/(1+ bm), which simulates the functional form of ƒ (m)=[1− exp (-am)]/a …

Results of experiments on the dynamics of scattering in barium titanate are presented.
Asymmetric scattering and centrosymmetric scattering are characterized as a function of …

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 …

On the basis of the standard model for the photorefractive nonlinearity we investigate
whether a systematic description of the dependence of two-beam energy exchange on …

A laser beam incident on BaTiO 3 can cause a cone of light to exit the crystal. If the incident
beam is polarized as an extraordinary ray, the cone of light is formed by ordinary rays. The …

We develop a theory of vectorial wave coupling in cubic photorefractive crystals placed in an
alternating ac field to enhance the nonlinear response. It is proven in the general case that …
