| 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. |
