摘要：

The development of femtosecond laser systems has opened the door to studying ultrafast dynamical processes, which range from nuclear motion in molecules to relaxation mechanisms of charge carriers in solids. A characteristic of the approach is that the system investigated is no longer in thermodynamic equilibrium. It is rather in an excited state whose decay into other degrees of freedom is being probed. We will, in this article, outline the general experimental set-up needed for such studies and discuss typical experiments involving excited electrons in solids.
