Abstract
We measured the third-order nonlinear optical susceptibility chi(3) fo r C60 and C70 SolUtions as a function of concentration using degenerat e four-wave mixing with picosecond pulses at 532 nm. From the observed minimum we were able to obtain the real and imaginary parts of chi(3) . The real part is negative at this wavelength. Values of the real and imaginary components of the molecular hyperpolarizability (gamma) cal culated are in the range 10(-31) esu.
