Excited state refraction of C70/toluene studied by using 4f coherent imaging system with phase object
【摘要】 Dynamic nonlinearities of C 70 /toluene solution are measured and analysed by an improved picosecond time-resolved pump-probe system based on a nonlinear imaging technique with phase object.The photophysical parameters are determined by the five-level model,which is adopted to interpret the experimental data.The change of refraction index per unit density of the excited state obtained by a numerically simulation is a critical factor to determine the nonlinear behaviour of C 70 in picosecond time regime.
