Abstract

By using the second harmonic generation of the nanosecond and picosecond laser systems, we have studied the degenerate four-wave mixing from the C₆₀ and C₇₀ molecules. In nanosecond regime, the thermal effect contributes greatly to the measured signal, but in picosecond case, the thermal process and the electronic process which both contribute to the signal could be completely temporally separated. From time-resolved four-wave mixing measurement, the third-order optical susceptibility of C₆₀ was estimated to be (3.6 + 1.4)*10^-10 esu at 532 nm which is in agreement with recent measurement results.113b
