Paper Abstract

A laser-diode interferometer with a self-pumped (cat) phase- conjugate mirror is presented. The phase is shifted to produce a spatially uniform phase change uncancelled by a phase conjugator between the two beams of an interferometer. An ac interferometer would be realized by means of heterodyne techniques that can be employed by modulating the phase of the conjugate wave by using the frequency-ramped laser diode (LD). In the interferometer, the uniform phase change of a single input is not reserved upon phase conjugation, while relative phases between two inputs are reversed. Effect of cross talk between two input amplitudes on phase-conjugate interferometric phase has been studied. Experimental results are shown.
