Two coherent or incoherent stable self-pumped phase conjugations have been obtained simultaneously in a Ce-doped (K 0.5 Na 0.5 ) 2y (Sr 0.61 Ba 0.39 ) 1-y Nb 2 O 6 (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%.
