The full wealth of quantum kinetics can be tested by time-resolved femtosecond two-pulse spectroscopy either in the form of pump-probe spectroscopy or in the form of four-wave mixing. It is shown that pump-probe spectroscopy is amenable to follow the temporal evolution of the particle distributions. This is illustrated by calculations and experiments on the buildup of phonon cascades and on non-Markovian relaxation scenarios. Four-wave mixing, on the other hand, is shown to be well-suited for the study of quantum coherence and its dephasing illustrated by LO-phonon quantum beats.
