Abstract
Optical phase conjugation in various photorefraetive media has been studied over the past ten years. It has been employed in many promising applications such as optical information processing, laser phase-locking, communication, interferometry, and so on1,2 Among various self-pumped phase conjugators, it has been shown both experimentally and theoretically that self-pumped ring phase conjugator (Ring SPPC) has the characteristics of low oscillation threshold and high and stable output.1-3
