Time-resolved DFWM spectroscopy of fullerene in toluene and glass

To summarize, addition of C/sub 60/ to solvent and glass matrix increases the LIPS signal by at least an order of magnitude while decreasing the coherence peak by a factor of 3.4 in C/sub 60/-toluene, and a factor of 5.3 in C/sub 60/-toluene. Such an effect may result in erroneous calculations of third order nonlinear susceptibility which are based on comparison of the coherence peak with a standard of CS/sub 2/.<
