Abstract : The present invention relates to the modulation of a phase conjugate beam. A writing beam is directed incident to phase conjugate reflector. A modulating beam is also directed incident to the phase conjugate reflector for amplitude modulation of the phase conjugate beam. The modulating beam can also be steerable for effecting the amplitude of the phase conjugate beam according to spatial distribution so as to spatially modulate the phase conjugate beam. The phase conjugate modulation thus can be accomplished by opto-optical means and without modulation of or effect on the incident writing beam. Keywords: Patents, PAT-CL-350-354. (JES)
