In this study, we investigate the performance of a high-efficiency KNSBN:Cu double phase-conjugate mirror (DPCM). A phase-conjugate transmissivity as high as 58% and a phase-conjugate reflectivity as high as fivefold are observed. Experimental results also show that the DPCM has a good fidelity of phase-conjugate image. Also, amplified phase-conjugate images are observed.
Key words : double phase-conjugate mirror, KNSBN:Cu crystal, phase-conjugate image, image fidelity, phase-conjugate transmissivity, phase-conjugate reflectivity
