摘要
The third-order nonlinear optical (NLO) susceptibilities of anthraquinone and its derivatives have been calculated by both finite-field (FF) and time-dependent coupled-perturbation Hartree-Fork (TDHF) methods. It shows that the susceptibilities of 2, 6-disubsituted anthraquinone derivative are larger than those of any other disubstitutes, The stronger electronic donors are found to be favorable to reach larger NLO polarizabilities. The frequency-dependent NLO susceptibilities, which are larger than static ones, increase with the increasing frequencies of applied field.
