摘要：
We present the optical response of solutions of C60 and C70 fullerenes to high-intensity visible laser pulses. A decrease of the transmission with increasing input intensity is observed at different wavelengths. The measurements are compared with simulations using a rate equation model. Excited-state absorption cross sections are evaluated and used to calculate the imaginary part of the resonant nonlinear susceptibility chi(3).
