dc.description.abstract We discuss some properties of the nonlinear absorption spectrum of insulators with a gap originating from the electron correlation. We formulate a method of evaluating the nonlinear susceptibility and apply this to the antiferromagnetic insulator. A scaling relation for two-photon absorption is derived and applied to a quantitative estimation, which gives values comparable to those of experiments on Mott insulators. The direct transition term is found to be dominant in many-body systems. It is also shown that our formulation naturally includes the final-states interaction (the charge fluctuation and the excitonic effect), which gives a sufficient contribution to the two-photon absorption spectrum.
