中文摘要：

采用365 nm的门光束和633 nm的记录光在LiNbO3：Fe：Cu晶体（Fe：0.15%,Cu：0.01%）中实现了双色记录和无损读出.依据双色复用记录中的擦除特性,采用合适的曝光时序,在LiNbO3：Fe：Cu晶体中实现了50幅全息光栅的双色复用记录和固定,衍射效率基本相等,平均固定效率达到61%,在3.0 mm的晶体中固定后的动态范围M/#为2.2.

英文摘要：

Persistent holographic recording is implemented in LiNbO3 ： Fe ： Cu crystal with a gating light at 365 nm and a recording light at 633 nm. 50 planewave holograms with almost equal diffraction efficiencies are multiplexed in a LiNbO3 ： Fe ： Cu crystal by using a recording schedule. The average fixing efficiency reaches 61 % ,and the dynamic range M/# for twocolor holographic storage is estimated to be 2.2.
