摘要
本文报道了利用单光束方法研究C60/C70甲苯溶液的非线性光学性质,C60/C70的浓度为3.5×10-3 mol,C60:C70=3:1,实验所用的泵浦光源为被动锁模Nd:YAG激光器,脉宽40ps,实验给出C60/C70溶液的非线性折射率n2=(2.3±0.3)×10-11 esu,并给出三阶超极化率r=1.1×10-31 esu。
Abstract
A single light beam method for measuring the nonlinear optical index of C60/C70 in toluence solution at picosecond range is reported. The concentration of C60/C70 is 3.5×10-3 mol, and the content of C60 to that of C70 is 3:1. The pump beam with 40ps width was generated by an passive mode-locking Nd:YAG laser. The nonlinear refractive index of C60/C70 solution is n2=(2.3±0.3)×10-11 esu, the average hyper-susceptibility γ=1.1×10-31 esu.
