The third-order nonlinear optical properties of C60/poly(dimethylacetylendicarboxylate) have been studied using Z-scan technique. Experiments are performed using a CW diode laser at 635 nm wavelength and 26 mW power. The nonlinear absorption coefficient β, nonlinear refractive index n2, Reχ3, and Imχ3 in C60 doped poly(dimethylacetylendicarboxylate) are measured using Z-scan data. Our results show that the values of the nonlinear optical parameters (β, n2, Reχ3, and Imχ3) of C60 doped poly(dimethylacetylendicarboxylate) are smaller than the polymer itself.
