Fast modeling of regenerative amplifier free-electron lasers

Physical Review Research, 2023
High-gain free-electron lasers (FELs) are becoming important light sources at short wavelengths such as the EUV and x-ray regimes. A particularly promising concept is the regenerative amplifier FEL (RAFEL), which can greatly increase the brightness and ...

Broadband optical gain via interference in the free electron laser: principles and proposed realizations [PDF]

, 2001
We propose experimentally simplified schemes of an optically dispersive interface region between two coupled free electron lasers (FELs), aimed at achieving a much broader gain bandwidth than in a conventional FEL or a conventional optical klystron ...

Tunability of free-electron lasers [PDF]

, 1995
In a free-electron laser oscillator, a variation in the electron beam energy leads to a change in the resonant optical frequency. Simulations are used to study the optical response to an electron beam energy change.

High average current electron guns for high-power free electron lasers

Physical Review Special Topics. Accelerators and Beams, 2011
High average power free-electron lasers (FELs) require high average current electron injectors capable of generating high quality, short duration electron bunches with a repetition rate equal to the frequency of the rf linac.

Recirculated Wave Undulators for Compact FELs

Applied Sciences, 2021
Particular schemes of Free Electron Lasers (FELs) are designed to exploit wave undulators. We consider a system employing a recirculated electromagnetic undulator provided by a high-power laser in a resonator cavity.

Imaging atom-clusters by hard x-ray free electron lasers [PDF]

, 2003
The ingenious idea of single molecule imaging by hard x-ray Free Electron Laser (X-FEL) pulses was recently proposed by Neutze et al. [Nature,406,752(2000)].
