The coupled wave equations for four-wave mixing (FWM) in a cubic, non-optically-active
photorefractive crystal are solved for the case of orthogonally polarized pumping beams. For …

If a single laser beam is incident on a photorefractive crystal of barium titanate, a phase-
conjugate beam can emerge. 1 Nature seems to have a proclivity for producing the phase …

A photorefractive system based on the combined operation of a strontium barium niobate
input amplifier and a self-pumped barium titanate phase-conjugator crystal is presented and …

We report the design and operation of a photorefractive ring self-pumped phase conjugator
using total internal reflection in strontium barium niobate. Phase-conjugate reflectivity and …

A numerical method to simulate the photorefractive phase conjugation process in rather
general conditions, pump depletion and multigrating operation, has been developed …

Theoretical considerations and experimental results are presented for simultaneous
degenerate multi-wave mixing in photorefractive BSO. Using the same crystal volume and …

The threshold for self-pumped optical phase conjugation by means of backward stimulated
photorefractive scattering has been dramatically lowered by inserting a retroreflecting …

In this letter, we present the results of two-wave mixing experiments performed with several
BaTiO:> crystals in the temperature range between 20 and 125" C. Earlier publications by …

A self-pumped forward phase-conjugate mirror based on nonlinear wave mixing in
photorefractive media is demonstrated. A single input beam to a BaTiO_3 crystal excites an …

Transient high diffraction efficiency of phase-conjugate output in a photorefractive crystal of
BaTiO3 was measured for the case in which the reading beam illuminates the transmission …
