Abstract
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-conjugate beamf and here I will discuss some of our recent experimental attempts to understand this phenomenon. This study is motivated by a search for a new kind of optical computer, one that can take entire patterns, or images, and transform them to other images. We already know how to do this on a limited scale; for example, we know how to use four-wave mixing to produce the correlation pattern between two images.2 However, what I’d like to discuss here is somewhat different, in that it involves a stimulated process.
