Experimental Study of Non-volatile Holographic Storage of Doubly- and Triply-doped Lithium Niobate Crystals
【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 niobate crystals doped with Cu∶Ce, Mn∶Cu∶Ce, Mn∶Fe, and Mn∶Fe∶Mg, which are processed under two different oxidation/reduction conditions, have been studied experimentally for non-volatile holographic storage with ultraviolet and red light. The non-volatile holographic storage in LiNbO 3∶Cu∶Ce and LiNbO 3∶Cu∶Ce∶Mn crystals is realized. The results show that higher oxidized crystals may realize non-volatile holographic storage. The persistent diffraction efficiency of non-volatile holographic storage of LiNbO 3∶Cu∶Ce crystal is the largest on the premise of high signal-to-noise.
