Abstract

We have extended the wavelength range of our previous study of the third order nonlinear optical susceptibility tensor (chi) ⁽³)(-(omega) , (omega) , (omega) , -(omega) ) of a thin C60 film to 1.7 micrometers . We use time-resolved degenerate four-wave-mixing with femtosecond pulses to measure both the phase and magnitude of (chi) ₁₁₁₁. Our data are well defined in terms of a single two-photon resonance at a fundamental wavelength of 930 nm. From our fit parameters, we predict for (chi) ₁₁₁₁ in the zero-frequency limit a value of (9 +/- 3) X 10^-13 esu and at the resonance maximum a value of i(3.9 +/- 0.6) X 10^-12 esu.
