摘要：

Damping, the effects of uncertainty, Doppler, collisional, and other mechanisms that lead to the broadening of electronic transitions are rarely accounted for in the calculation of optical nonlinearities. Using the two-level model as an illustration, this work points out that damping corrections can be substantial for organic compounds, even for two- or three-photon resonances, and that these corrections are dependent on molecular symmetry. Comparisons of calculated and measured susceptibilities need to take this into account. Results are presented for the quadratic electro-optic, third-harmonic, and electric-field-induced second-harmonic-generation processes. © 1990 The American Physical Society.
