Abstract
Using the density‐matrix formalism, the dielectric function of athree‐level system under high excitation conditions is determined. The density matrix being calculated by a continuous matrix inversion, non‐resonant contributions and saturation effects can be fully accounted for and the stability of absorption and dispersion anomalies may be discussed.Keywords
