Dispersion and Absorption Anomalies in Three‐Level Systems
B. Hönerlage, J.‐Y. Bigot
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.
