摘要We investigate the third-order nonlinear optical properties of six novel ullerene derivatives under picosecond laser excitation by Z-scan technique. The experimental results reveal that all the derivatives have very large nonlinear absorption coefficient under 532nm pulses excitation and great third-order nonlinear refraction index under 1064nm pulses excitation. The molecular second hyperpolarizabilities are obtained from the experimental results.
