Paper Abstract

Obtaining self-pumped phase conjugation in photorefractive crystals without the use of external mirrors usually requires that the crystals exhibit significant beam fanning and have large gain-length products. Large variations in the phase conjugate reflectivity and response time can occur with changes in the incident beam location relative to the corner cube. This paper explores experimentally the dependence of the phase conjugate reflectivity and the response time on the incident beam location in a Ce-doped SBN:60 crystal. Beam erasure at selective sites within the crystal is used to determine the location of the self-organized gratings.
