Phase conjugation revisited
David C. Brown, Kotik K. Lee
Abstract
We have proved, by using nonlinear wave equation among three independent methods, that: complete correction of phase distortions due to an optical device (or a system of several optical devices) by phase conjugation is possible if and only if the device (or the system) which produces such phase distortion is gainless, lossless, and time‐order invariant. Effects of saturated gain, finite coherence, and system symmetry are also discussed briefly.
