Free-electron laser (FEL) devices are radiation sources with a wide tunability ranging from far-infrared up to X-rays. All existing FELs can be described by classical electrodynamics. However, due to experimental progress in the last years a new regime, the so-called quantum regime seems to be in reach.

Here recoil effects become important and a Jaynes-Cummings-like behavior between the radiation and the center-of-mass motion arises. Within our approach we investigate its emergence as well as its properties. In contrast to earlier approaches based on quantum mechanics in a co-moving reference frame we stay in the laboratory frame and use quantum electrodynamics.
