Paper Abstract

Using Si-Mo Bar as the heater, potassium sodium barium strontium niobate (KNSBN) crystals doped with Ce and/or Eu have been grown by the Czochralski method. The exponential gain coefficients were measured by two-wave coupling light path, and in comparison with KNSBN, that of Ce:Eu:KNSBN is one time higher. Holographic associative storage principle is represented here and the holographic associative storage is realized by using Ce:Eu:KNSBN as the storage element and Mg:Fe:LiNbO3 as the phase conjugator to feedback, fetch threshold and gain. The output images are integrated.
