Abstract

We report the (chi) ⁽³)(-3(omega) ;(omega) ,(omega) ,(omega) ) of a thin film of polycrystalline C₆₀ on glass measured by third harmonic generation (THG) over the fundamental energy range of 0.52 - 1.18 eV. The dispersion clearly shows a three-photon resonance at $HBAR(omega) equals 0.94 eV, whose third harmonic energy corresponds to the dipole allowed transition at 2.8 eV in the solid C₆₀. We use perturbation theory to model the linear absorption spectrum and the nonlinear spectrum, and achieve consistent values for the fitting parameters.
