The light-induced changes of the properties of a semiconductor caused by an ultra-short strong laser pulse with a central frequency well below the fundamental absorption edge are investigated. Renormalization and time evolution of one- and two-particle properties are discussed using a nonequilibrium Green's function formalism. Numerical results for the absorption spectra are presented.
