On the Quantum Theory of the FEL — •Paul Preiss1, Roland Sauerbrey2, and Wolfgang P. Schleich1 — 1Institut für Quantenphysik, Universität Ulm, D-89069 Ulm, Germany — 2Forschungszentrum Dresden-Rossendorf, D-01328 Dresden, Germany
The free-electron laser (FEL) is an alternative laser device with a widely tunable wavelength of the emitted radiation. Usually, FEL’s operate in the so-called classical regime where quantum effects can be neglected. Recent developments in accelerator and laser physics permit the realization of a FEL in the quantum regime. We discuss the effects emerging in a quantum FEL by considering the time evolution of the density operator of the system.
