Paper 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.
