| 摘 要： | 合成了嘧啶环二炔氮桥C60衍生物C60NPD ,研究了在532nm、脉宽 8ns条件下的非线性光学特性。通过Z-扫描实验发现C60NPD有很强的非线性吸收和非线性折射,并获得了三阶非线性光学系数χ(3) 。同时也研究了光限幅特性，实验结果表明C60NPD有较低的光限幅箝位值。

| Abstract: | Aza-bridged [60] fullerene derivative C60NPD was synthesized and the nonlinear optical properties of C60NPD were measured using a Q-switched Nd:YAG laser with 8ns pulse excitation at 532nm. The reverse saturation absorption and nonlinear refraction were observed by means of Z-scan technique and the value of third-order nonlinear optical susceptibilities χ(3) were obtained. The optical limiting properties of C60NPD were also studied and the results show that it has a good optical limiting performance. |
