We have measured the third-order susceptibility v h3i ijkl of a C 60 -TTF compounds in tetrahydrofuran (THF) solutions using the degenerate four wave mixing technique at k ΒΌ 532 nm in the picosecond regime. To know the physical nature of the optical non-linearities, we separate the electronic and nu
The nonlinear third-order optical susceptibility of C70 in a toluene solution is measured for the first time by the method of degenerate four-wave mixing using 10 ns laser pulses at 1.06 gin. The third-order susceptibility -( 3) is 5.6 x 10 12 esu for a C70 toluene solution at a concentration Xl11I
