摘　　要：为了研究一种新型双氮杂桥C_(60)衍生物的非线性光学特性,利用z扫描和光限幅实验分别研究了该化合物在532nm、脉宽8ns条件下的非线性光学和光限幅特性,并进行了理论分析和实验验证。结果表明,该化合物有较强的非线性吸收和非线性折射,非线性吸收系数β=1.92×10^(-10)m/W,3阶非线性系数χ^((3))=6.34×10^(-12)esu;化合物有较低的光限幅箝位值。该化合物是一种非常有前途的非线性光学材料。The nonlinear optical property and optical limiting property of a new diaza-bridged C60 derivative were studied by means of z-scan technique and experiment under irradiation of 8ns pulse duration at 532nm. The reverse saturation absorption and nonlinear refraction were observed by means of z-scan technique . The nonlinear absorption coefficient fl and the value of the third-order nonlinear optical susceptibilitiesx^3 were obtained respectively. The compound had lower value of the optical limiting clamp. All the results show that this compound has a good optical limiting performance.
