LiNbO3:Fe和LiNbO3:Fe:Mn晶体非挥发全息存储的理论研究
THEORETICAL STUDY OF NONVOLATILE HOLOGRAPHIC STORAGE FOR LiNbO3:Fe AND LiNbO3:Fe:Mn
摘要
以双中心模型为基础, 理论研究了连续光条件下近化学比LiNbO3:Fe和LiNbO3:Fe:Mn晶体在稳态情况下的非挥发双色二步全息存储性能.通过考虑在深、浅能级中心之间所有可能的电子交换过程, 从理论上证实了在低光强范围内LiNbO3:Fe晶体比LiNbO3:Fe:Mn晶体有着更大的空间电荷场、更高的记录灵敏度和动态范围.
Abstract
The steady-state nonvolatile two-step, two-color holographic storage performance for both LiNbO3:Fe:Mn and LiNbO3:Fe was investigated theoretically based on the two-center model. By considering all the possible electron transfer processes between the deep-trap and the shallow-trap centers, LiNbO3:Fe was confirmed theoretically to be of bigger space-charge field, higher recording sensitivity, and larger dynamic range than LiNbO3:Fe:Mn in the low intensity region.
