Frequency Dependence of Two-Photon Resonances and Damping in Polymers

Abstract

For the two photon resonance in the third-harmonic generation (THG) spectrum of trans-polyacetylene, the existing theories can only qualitatively rather than quantitatively explain 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 theoretical calculations.
