Free-Electron Lasers (FEL) provide coherent and widely tunable radiation of high brilliance. Most theoretical descriptions are based on classical physics in agreement with experimental results. However, in the near future an FEL working in the quantum regime is within reach at the Research Center Dresden-Rossendorf. Some theoretical progress has been made so far to understand quantum effects which are usually suppressed in the classical regime and therefore ignored. This includes two-level photon transitions, significant recoil effects, phase diffusion and much more. Based on our earlier work, we take a closer look at the density matrix of the joint system of laser field and electron beam. In this way we will analyze the behavior of both systems and, in particular, the photon statistics of the field and the microbunching of the electrons with the corresponding reduced density matrices.
