| 摘 要： | 为了研究一种新的有机金属配合物dmit盐(tetram ethylammon ium)bis(1,3-dithiole-2-thione-4,5-dithiolato)copper(简称为MeCu)的三阶非线性光学性质,采用单光束z扫描技术,在波长为1064nm、脉宽为30ps条件下对浓度为1.0×10-3mol/L的MeCu/丙酮溶液进行研究。实验结果表明,其三阶非线性折射率n2和二阶分子超极化率γ分别为-2.15×10-11esu和1.94×10-30esu,未发现三阶非线性吸收的存在。表明该材料在全光开关等非线性光学器件的研制上可能具有潜在的应用价值。

| Abstract: | The nonlinear optical properties of a novel dmit2 salt:(tetramethylammonium)bis(1,3-dithiole-2-thione-4,5-dithiolato)copper(abbreviated as MeCu)are studied with z-scan technique at 1064nm with 30ps laser duration. The nonlinear refraction coefficient n2 and the second hyperpolarizability γ have been determined to be －2.15 x 10－11 esu and 1.94 x 10－30 esu,respectively. No nonlinear absorption is observed under this condition. All the results show that McCu is a potential material for nonlinear optical devices such as all-optical switches. |
