In general, the application of an electric field to a photorefractive material with optical activity
results in a change in the effective electro-optic coefficient, r eff, which, in turn, alters the …

We consider the process of nonstationary enhancement of the photorefractive effect through
the application of time-varying (square-wave) electric fields. By examining the full second …

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 …

By applying pulsed electric fields to photorefractive crystals, the two-wave mixing gain is
considerably increased. Unlike other enhancement techniques, the maximum gain is not …

We show that photorefractive materials having large electro-optic coefficients such as
BaTiO3 require relatively small electric field to induce sufficient phase mismatch for the …

This paper dealt with the experimental observation of enhanced four-wave mixing in BSO.
The method used involves sinusoidal phase shift in one of the pump beams. Due to this …

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 …

We obtain analytical solution to the slowly varying envelope wave equations describing two-
wave mixing in photorefractive crystals with arbitrary dependence of the gain and absorption …
