Observation of Self-pumped Phase Conjugation for Two Mutually Coherent Input Beams in a KNSBN Crystal
-
Abstract
Two coherent or incoherent stable self-pumped phase conjugations have been obtained simultaneously in a Ce-doped (K0.5Na0.5)2y (Sr0.61 Ba0.39)1-y Nb2O6(KNSBN) crystal by using two mutually coherent input beams from a He-Ne laser, and energy translation from one beam to another induces self-pumped phase conjugative reflectivity of one beam above 100%.
