The propagation of ultrashort light pulses in two-photon media is investigated on the basis of a density-matrix formalism for the molecular levels and a wave equation for the dynamics of the light fields. The simulation shows that the dynamic light–matter coupling and level dynamics lead to saturation effects and space-dependent pulse shaping that determine the dynamic response of the molecular medium.
