Reported are experimental investigations of a barium titanate self-pumped phase conjugate
mirror (SPPCM), where the pump waves are generated by means of a concave mirror. The …

It is shown that photorefractive wave-mixing gives saturable gain, saturable absorption and
Kerr-like nonlinear phase retardation. An analogy between photorefractive two-beam …

Optical phase conjugation, or time reversal, of an optical wave front is an important
technique to correct distortions in electromagnetic waves which are built up during …

We demonstrate the bistable behavior in a photorefractive self-pumped phase-conjugator
(SPPC) theoretically and experimentally. In the method, an incoherent erase beam is used …

This review paper contains three parts. The first part covers the photorefractive (PR) effect
and the processes [eg two-wave mixing (TWM) and four-wave mixing (FWM)] which are …
