Paper Abstract

Steady emission of a phase conjugated beam from a photorefractive BaTiO3 crystal is generally obtained via a self-pumping process when the four-wave mixing configuration emerges in the crystal, provided the two intense beams generated by an input beam travel, after the reflection from the corner of the crystal, along each other's path in opposite directions. However, sometimes many intense beams originate from the input beam and, after the reflection from the corner of the crystal, make several four-wave mixing configurations to produce a stable phase-conjugated beam. When the diameter of the input beam does not exceed 20 micrometers , the intensity profile of the phase conjugated beam is quite different from that of the input beam. The difference is a dark spot in the former beam. The size, location, and shape of the hole differ drastically depending on the input beam incidence angle and relative position of the input beam waist and the crystal center. The differences in the internal beam configuration in the BaTiO3 crystal for each phase conjugated are not as distinct as the differences in their pattern.
