Abstract
Doping CeO2 and Tb4O7 in KNSBN, the Ce:KNSBN crystal was grown. It is the first time that the crystal was grown by Czochalski. The phase conjugate reflectivity was measured to be the higher than 140% on transient state and to be higher than 90% on stable state. The out electric field can enhance the phase conjugate reflectivity on transient state. When EO equals 4 kv/cm2, the transient phase conjugate reflectivity R equals 168% and the stable transient phase conjugate reflectivity R equals 120%. Ce:Tb:KNSBN crystals pumping on self phase conjugate reflectivity goes up to 62%. Cu:KMSBN was used as recorder and Ce:Tb:KNSBN was used as self-pumped conjugate to realize holographic associative memory.
