Abstract

The materials ratio is compounded followed by the molecular formula Ba_0.5Sr_1.5K_0.5Na_0.5Nb₅O₁₅. Doping 0.05 wt% CeO₂ and 0.03 wt% Co₂O₃ in KNSBN, Ce:Co:KNSBN crystal was grown by Czochralski technique adopting SiMo heater furnace. The exponential gain coefficient, diffraction efficiency and response time of Ce:Co:KNSBN crystal were measured through two-beam couple light path. The phase conjugation reflect efficiency and response time of Ce:Co:KNSBN and Cu:SBN crystals were measured by four-wave mixing light path. The holographic associative storage were established by using Ce:Co:KNSBN crystal as recording apparatus and Cu:SBN crystal as phase conjugation lens. Addressing was operated by 75% and 50% images and the associative storage reappearing images are clear, complete and noise was small. The photo-refractive effects of Ce:Co:KNSBN crystal are more excellent than KNSBN crystal.
