Summary Discussion: Theoretical Aspects of XUV Free Electron Lasers

摘要

We briefly summarize the existing knowledge on XUV operation of Free-Electron Lasers. The standard classical anlaysis is valid until about 1 Angstrom wavelength if a high energy electron beam is used. If a low energy beam is used, the limiting wavelength is larger. Other topics discussed are electron shot noise, photon statistics, photon and electron quantum effects, coherence, high-gain collective effects, higher harmonics, and transverse optical effects.
