Abstract
By solving the Liouville equation, third-order nonlinear terms is found via iterative density matrix. Regarding the improved modeling, all frequency range is taken instead of weak absorptive limit. Considered process can be compared with saturation fitting for heavy-hole excitons in the InAs quantum well.
