| 摘 要： | 利用锁模Ｎｄ：ＹＡＧ激光器的５０ｐｓ和信频光输出对Ｃ_（６０）甲苯溶液及Ｃ_（６０）膜进行了时间分辨简并回波混频测量．从溶液及膜都观察到一个很快的非线性光学响应．而一个较长寿命的成分仅在溶液中见到．由实验结果可以推算得Ｃ_（６０）的近共振三阶非线性光学极化率为（３．６±１．４）×１０（－１０）ｅｓｕ．

| Abstract: | Time-resolved deSenerate four-wave mixins experiments were conducted on toluene solutions and film of C6o using the second harmonic generation of a 50 picosecond mode-locked Nd: YAG laser. A fast nonlinear optical response was observed from both Ceotoluene solutions and C6o film, and another iong-lived comPOnent was observed only from C6o toluene solutions. The near resonant third-order nonlinear optical susceptibility of Cio estimated from the experimental result of the film is about (3.6±1.4)×10-10 esu. |
