Abstract
During and shortly after a femtosecond laser pulse excitation of a sem iconductor, the carrier kinetics is drastically altered. At this early stage the Coulomb potential is still unscreened and there is essentia lly no energy conservation in the two-particle scattering events. This explains in a natural way the results of recent femtosecond spectrosc opy experiments.
