Abstract

C₆₀ and C₇₀ buckminsterfullerenes have attracted much attention in recent years because of their special structure. Recently, Blau et al^[1] presented the first measurement of the third-order nonlinear susceptibility in C₆₀-benzene solutions using 50-psec pulses at 1.064 μm. Here, we report our studies of the third-order optical nonlinearity in C₆₀ and C₇₀-toluene solutions using 30-psec pulses at 0.532 μm, which emphsize on the measurements of the tensor element ${\chi }_{1212}^{(3)}$.
