Abstract

For the two-photon resonance in the spectrum of third-harmonic generation (THG) of trans-polyacetylene, the existing theories can only qualitatively, rather than quantitatively, accord with the experimental data. In this paper a damping mechanism is proposed. It shows that once the excitation-dependent damping is taken into account, the whole experimental spectrum of the THG can be quantitatively interpreted by our theory.
