Abstract

Stoichiometric Ce:Mn:LiNbO₃ crystal was grown by the TSSG method for the first time. The congruent Ce:Mn:LiNbO₃ (CCe:Mn:LiNbO₃) crystal was grown by the Czochralski method. The lattice constant was tested. The lattice constant of the stoichiometric Ce:Mn:LiNbO₃ (SCe:Mn:LiNbO₃) crystal was less than that of CCe:Mn:LiNbO₃ crystal. The absorption spectrum of the crystals was tested, the absorption edge of SCe:Mn:LiNbO₃ crystal has violet shift comparing with that of CCe:Mn:LiNbO₃ crystal. The exponential gain coefficient, the concentration of effective carrier, diffraction efficiency and response time were tested. Those properties of SCe:Mn:LiNbO₃ crystal mentioned above have been improved. SCe:Mn:LiNbO₃ crystal possesses the property of holographic storage for long.
