The FERMI free-electron lasers [PDF]

Journal of Synchrotron Radiation, 2015
FERMI is a seeded free-electron laser (FEL) facility located at the Elettra laboratory in Trieste, Italy, and is now in user operation with its first FEL line, FEL-1, covering the wavelength range between 100 and 20 nm. The second FEL line, FEL-2, a high-gain harmonic generation double-stage cascade covering the wavelength range 20–4 nm, has also ...

Low emittance injector design for free electron lasers

Physical Review Special Topics. Accelerators and Beams, 2015
Several parameters determine the performance of free electron lasers: the slice and the projected emittance, the slice energy spread, and the peak current are the most crucial ones.

Photonic Free-Electron Lasers

IEEE Photonics Journal, 2012
A photonic free-electron laser (pFEL) produces coherent Cerenkov radiation from a set of parallel electron beams streaming through a photonic crystal. The function of the crystal is to slow down the phase velocity of a copropagating electromagnetic wave,

Modelling elliptically polarised free electron lasers

New Journal of Physics, 2016
A model of a free electron laser (FEL) operating with an elliptically polarised undulator is presented. The equations describing the FEL interaction, including resonant harmonic radiation fields, are averaged over an undulator period and generate a ...

Short Rayleigh length free electron lasers

Physical Review Special Topics. Accelerators and Beams, 2006
Conventional free electron laser (FEL) oscillators minimize the optical mode volume around the electron beam in the undulator by making the resonator Rayleigh length about one third to one half of the undulator length.
