Abstract
High-order optical nonlinearities of C-60-toluene solutions were obser ved employing the transient degenerate four-wave mixing technique usin g 0.5 ps laser pulses at 497 nm. The intensity and fullerene concentra tion dependence of fifth- and seventh-order signals were investigated. The effect of the nonlinear absorption on the nonlinear optical respo nse is examined. The ratios \chi(eff)((5))\/\x((3))\ and \chi(eff)((7) )\/\chi(eff)((5))\ are determined to be of the order of 10(-10) cm(3) erg(-1).
