A free-electron laser (FEL) is usually considered a classical device since its dynamics can be fully described within classical electrodynamics. The reason for this fact is the parameter regime wherein the state-of-the-art devices operate. However, there exists a quantum regime [1, 2], where a quantum mechanical model of the process is definitely required.
Starting from a quantum mechanical description of the FEL within Wigner phase space, we trace back the emergence of quantum effects depending on specific parameters, e. g. the strength of the fields, or the initial momentum spread compared to the quantum mechanical recoil.
