Dispersion of the Third-Order Nonlinear Optical Susceptibility in C_{60} Calculated with a Tight-Binding Model

Kikuo Harigaya, Shuji Abe

The frequency dependence of third harmonic generation (THG) in C_{60} is calculated, making use of a tight-binding model for pi-electrons. The magnitudes of the THG, about 10^{-12}…
