Fresh-slice multicolour X-ray free-electron lasers

Nature Photonics, 2016
A new scheme for multicolour X-ray free-electron lasers at soft X-ray wavelengths is proposed. The scheme significantly improves two-colour pulse generation and makes possible the first demonstration of three-colour pulse generation.

An ultra-compact x-ray free-electron laser [PDF]

New Journal of Physics, 2020
Abstract In the field of beam physics, two frontier topics have taken center stage due to their potential to enable new approaches to discovery in a wide swath of science. These areas are: advanced, high gradient acceleration techniques, and x-ray free electron lasers (XFELs).

Optical Shaping of X-Ray Free-Electron Lasers.

Physical Review Letters, 2016
In this Letter we report the experimental demonstration of a new temporal shaping technique for x-ray free-electron lasers (FELs). This technique is based on the use of a spectrally shaped infrared (IR) laser and allows optical control of the x-ray generation process.

Time dependence of Bragg forward scattering and self-seeding of hard x-ray free-electron lasers [PDF]

, 2012
Free-electron lasers (FELs) can now generate temporally short, high power x-ray pulses of unprecedented brightness, even though their longitudinal coherence is relatively poor.

Attosecond-Angstrom free-electron-laser towards the cold beam limit

Nature Communications, 2023
Free-electron lasers (FELs) can produce bright X-ray pulses, but require high quality electron beams. Here the authors show how to generate and preserve ultrabright electron beams from plasma-based accelerators for ultra-compact, high-brightness X-ray ...
