光折变晶体 稳定全息存储 双掺杂和三掺杂 photorefractive crystal non-volatile holographic storage doubly-and triply-doped
摘要
对两种不同氧化/还原处理下的四种不同掺杂Cu:Ce,Mn:Cu:Ce,Mn:Fe和Mn:Fe:Mg的铌酸锂晶体进行了红光和紫光光色效应稳定全息存储的实验研究,实现了LiNbO3:Cu:Ce和LiNbO3:Mn:Cu:Ce晶体中的稳定全息存储。实验结果表明只有高氧化的晶体才能实现稳定全息存储。在高信噪比前提下,LiNbO3:Cu:Ce晶体稳定衍射效率最高。
Abstract
Four lithium niobatecrystals doped with Cu:Ce, Mn:Cu:Ce, Mn:Fe, and Mn:Fe:Mg, which are processed under two different oxidation/reductionconditions, have been studied experimentally for non-volatile holographic storage withultraviolet and red light. The non-volatile holographic storage in LiNbO3:Cu:Ce and LiNbO3:Cu:Ce:Mn crystals is realized. The results show that higher oxidizedcrystals may realize non-volatile holographic storage. The persistent diffractionefficiency of non-volatile holographic storage of LiNbO3:Cu:Ce crystal is the largest on the premise of high signal-to-noise.
