The possibility of phase conjugate mirrors (PCM's) with reflectivities exceeding unity was
predicted by Yariv and Pepper, I and subsequently observed by Bloom, Liao, and …

Sinusoidal intensity oscillations of the phase conjugated wave reflected from a self-pumped
photorefractive BaTiO 3 crystal have been observed. The oscillation amplitude is shown to …

Recent developments, both theoretical and experimental, involving the nonlinear
interactions of light in photorefractive crystals are reviewed. When pumped by light beams in …

We present theory and experiments to show that the efficiency of four-wave mixing in
photorefractive materials can be enhanced by use of optical waves of slightly different …

The ability of photorefractive crystals such as barium titanate and strontium barium niobate
to record spatially phase shifted real time holograms with high diffraction efficiency is the …

We report coherent oscillations due to self-induced moving gratings in photorefractive BSO
crystals when recording with an external applied field. Different types of ring and phase …

crystals Page 1 IEEE JOURNAL OF QUANTUM ELECTRONICS, VOL. QE-22, NO. 8 …

The development of a theory of four-wave mixing in photo-refractive crystals is described.
This theory is solved in the undepleted pumps approximation with linear absorption and …

Two mutually incoherent extraordinary laser beams, incident upon opposite a faces of a
BaTiO_3 crystal, generate a set of photorefractive holograms that channel both beams …

We have characterized the photorefractive performance of a special 45°-cut crystal of
BaTiO_3 and compared it with the conventional 0°-cut material. An increased peak gain …
