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.

X-Ray Free Electron Lasers [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2017
In a free-electron laser (FEL) the lasing medium is a high-energy beam of electrons flying with relativistic speed through a periodic magnetic field. The interaction between the synchrotron radiation that is produced and the electrons in the beam induces a periodic bunching of the electrons, greatly increasing the intensity of radiation produced at a ...

On Free-Electron Laser Growing Modes and their Bandwidth [PDF]

, 2011
Free-electron lasers play an increasing role in science, from generating unique femtosecond X- ray pulses for single short recording of the protein structures to amplifying feeble interactions in advanced cooling systems for high-energy hadron colliders.

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).

Vacuum birefringence at x-ray free-electron lasers

New Journal of Physics, 2021
We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone.

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 ...

Transient nuclear inversion by x-ray free electron laser in a tapered x-ray waveguide

Physical Review Research, 2022
The enhancement of x-ray-matter interaction by guiding and focusing radiation from x-ray free electron lasers is investigated theoretically. We show that elliptical waveguides using a cladding material with a high atomic number, such as platinum, can ...
