ABSTRACT:
Self-pumped phase conjugation is achieved for optical beams with very short pulse durations by a transient energy transfer mechanism. A probe beam is transmitted through a non-linear optical medium, generating a noise beam from the medium. The probe and noise beams are directed along equal time duration paths, preferably contra-directional to each other, back into the non-linear medium where they mix with each other. The peak probe pulse is thus mixed with the peak noise pulse to optimize gain. The thickness and optical coupling coefficient of the non-linear medium, and the angle between the returned probe and noise beams, are selected to produce a noise beam gain which is sufficient to generate a phase conjugate of the input probe beam.
