研究了加合不同取代基团的C60醛类衍生物的光学非线性性质。利用简并四波混频（DFWM）方法获得了C60醛类各衍生物的三阶光学非线性超极化率γ(3)及相应的三阶光学非线性系数χ(3)值。同时也研究了它们各自的光限幅特性。结果表明：不同的取代基对C60醛类衍生物三阶光学非线性及光限幅特性的影响不同。

The nonlinear optical properties of a series of C60 derivatives with different substituents are reported. The optical limiting properties were measured using the second harmonic of a Q-switched Nd∶YAG at 532 nm, the third-order optical nonlinearities of C60 derivatives in solution were studied by nanosecond degenerate four-wave-mixing(DFWM) experiment. The values of the third-order hyperpolarizabilities γ(3) and the third-order nonlinear optical susceptibilities χ(3) of C60 derivatives were obtained, respectively. Experimental results show that different substituents have different effects on the nonlinear optical properties of C60 derivatives.
