Quantum free-electron laser: single- and multiphoton transitions — •Peter Kling1 and Enno Giese2 — 1Deutsches Zentrum für Luft- und Raumfahrt e.V.

The quantum free-electron laser (``Quantum FEL") is a proposed x-ray source. In contrast to existing devices (``classical FEL"), where an electron in the undulator follows continuous trajectories and emits many photons, an electron in the Quantum FEL occupies only two resonant levels on a discrete momentum ladder and emits at most one photon. We investigate the influence of multiphoton corrections [1] on the dynamics of the electron and on the photon statistics of the emitted radiation. Moreover, we (i) try to identify the challenges for an experimental realization [2] and (ii) study the transition between classical and quantum regime in the FEL from a fundamental point of view [3].
