Resonances and radiation features of a quantum free-electron laser — •Peter Kling1, Enno Giese2, C. Moritz Carmesin3, Roland Sauerbrey4, and Wolfgang P.

In the quantum regime of a free-electron laser (FEL) the quantum mechanical recoil, an electron experiences during the scattering from photons, dominates the dynamics of the electron-light system. Energy-momentum conservation combined with the discreteness of the recoil lead to narrow resonances for the electron momentum. We investigate the time scales of the dynamics as well as the features of the emitted radiation from such a Quantum FEL for different resonant momenta.
