摘　　要：主要研究叶绿素铜纳盐溶液,以及加入氯化钠之后的混合溶液的光学非线性效应,为水下激光通信、强激光水下探测等应用提供了一些参考价值。研究采用Z扫描技术分别测量了纯水和混合氯化钠的叶绿素铜纳盐溶液在532 nm处的光学非线性效应。研究发现,叶绿素铜纳盐的光学非线性效应随着溶液浓度增大而增大;当混合了氯化钠溶液之后,出现了非常大的非线性反饱和吸收现象。因此,这种混合溶液可以作为非常好的光限幅材料。In this paper, we characterize the nonlinear optical properties of copper chlorophyllin sodium salt solution and and mixed solution with sodium chloride, which provides some reference value for underwater laser communication, high intensity laser underwater detection, and other applications of intense light. In this study, the optical nonlinear effects of pure water and copper chlorophyll-sodium salt solution mixed with sodium chloride at 532 nm were measured by z-scanning technique. It is found that the optical nonlinear effect of copper chlorophyllin sodium salts increases with increaseing the concentration. However, when mixed with sodium chloridesolution, there is a distinct nonlinear anti-saturation absorption. Therefore, this hybrid material is a very good optical limiting material.
