以双中心模型为基础,研究了连续光条件下近化学计量比LiNbO3:Fe和LiNbO3:Fe:Mn晶体在稳态情况下的非挥发全息存储性能。考虑在深、浅能级中心间所有可能的电子交换过程,从理论上证实在低光强范围内LiNbO3:Fe晶体比LiNbO3:Fe:Mn晶体有着更高的动态范围。
Based on the bivariate model, the non-volatile holographic storage properties of near-stoichiometric LiNbO3: Fe and LiNbO3: Fe: Mn crystals under steady-state conditions were studied. Considering all possible electron exchange processes between deep and shallow level centers, it is theoretically confirmed that LiNbO3: Fe crystals have a higher dynamic range than LiNbO3: Fe: Mn crystals in the low light intensity range.
