摘要
合成了一种新型有机金属配合物 Cetyltrimethylammonium-bis(2-thioxo-1,3- dithiole- 4,5-dithiolato)-copper(简称 CtCu)材料.采用单光束 Z 扫描测试技术,在波长为 1053 nm,脉宽为1 ns的务件下研究了该样品的三阶非线性光学性质.研究发现,该材料具有很强的饱和吸收特性,激发态的有效吸收截面为σeff= 1.10×10-19 cm2,与基态吸收截面的比值为 1∶484.利用非线性透过率实验验证了材料的饱和吸收特性,并对其产生机理进行了分析.实验结果表明,该材料在近红外波段的激光脉冲压缩方面有潜在的应用前景.
