It is shown that even slight optical feedback of a self-pumped phase-conjugate signal into dye or argon-ion lasers causes laser wavelength and conjugator reflectivity changes. The wavelength dependence of the self-pumped phase-conjugate reflectivity in barium titanate is examined over most of the visible spectrum. It is also demonstrated that interference between two collinear beams incident upon the conjugator affects the behavior of the phase-conjugate mirror.
