ABSTRACT
A self-pumped phase conjugating mirror in conjunction with a traveling-wave acousto-optic modulator can be used to derive a spatially undisplaced frequency translatable optical beam. One can also obtain a beam consisting of multiple optical frequencies spaced by twice the modulator drive frequency. We find that the appropriate measure of the phase conjugating mirror's ability to retroreflect a moving optical beam can be its response (writing) time, its memory time, or the ratio of the two, depending on how the beam is moving.
