Optical phase conjugation with frequency up-conversion via high-order, nondegenerate multiwave mixing

Abstract

One proposes a new way of getting optical phase conjugation, associated to frequency conversion (namely, frequency doubling, frequency multiplication or mixing), within a broad angular field of view. This technique is based on nondegenerate, higher order multiwave mixing in a phase-matched backward configuration. Applications to wave front reversal, spatial or temporal information processing with frequency up-conversion are outlined.
