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

The gain–length product for two-wave mixing in photorefractive BaTiO_3 is calculated as a
function of the angles between a pump beam and a scattered beam and the crystal c axis …

The temporal evolution of nonlinear scattering which is induced by simultaneous action of
an ordinary and an extraordinary wave impignig on a photorefractive crystal in the plane …

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 …

We study the mechanism by which parametric scattering couples orthogonally polarized
light waves in photorefractive BaTi03. We obtain explicit relationships that link the efficiency …

It is shown experimentally that the nonsymmetric behavior of the beam-coupling gain
coefficient of BaTiO_3 crystals with respect to the sense of the c axis is caused by an …

We present an experimental investigation of the phase conjugate reflectivity as a function of
angular deviation from collinearity of the pump waves in BaTiO 3. In that case of four-wave …

We demonstrate a new method of light amplification based on forward four-wave mixing in
photorefractive BaTiO_ 3. A single pump beam of combined (ordinary and extraordinary) …

The influence of the piezoelectric and photoelastic effects is experimentally demonstrated in
barium titanate (BaTiO 3). Its effect on the photorefractive two-beam coupling is investigated …
