Abstract
Phase-locked phase conjugation is the process in which a number of beams are phase conjugated, with the phase conjugates having the same relative phases as the original beams. The concept for the case of two beams is shown in Fig. 1. When ideal phase locking is achieved, all of the returning phase-conjugate light travels back along the path of the beam incident on the beam splitter. In the case of imperfect phase locking, some of the phase-conjugate light is reflected from the beam splitter because of incomplete destructive interference in that direction.
