Abstract

The nonvolatile holographic storage of a near-stoichiometric LiNbO(3):Cu:Ce crystal with green light was investigated. With an increase in composition, improved nonvolatile holographic performance was obtained. The sensitivity S? of the near-stoichiometric LN(49.57):Cu:Ce crystal is 1 order of magnitude larger than the congruent crystal. And according to our research, Ce ions should be the deep centers of the LiNbO(3):Cu:Ce crystal.

摘要

研究了近化学计量比的LiNbO(3):Cu:Ce晶体绿光非挥发全息存储特性。随着组分增加，获得了改善的非挥发全息性能。近化学计量比的LN(49.57):Cu:Ce晶体的灵敏度S?比同成分晶体大1个数量级。并且根据我们的研究，Ce离子应为LiNbO(3):Cu:Ce晶体的深中心。
