Scientific Opportunities with an X-ray Free-Electron Laser Oscillator [PDF]

, 2019
An X-ray free-electron laser oscillator (XFELO) is a new type of hard X-ray source that would produce fully coherent pulses with meV bandwidth and stable intensity. The XFELO complements existing sources based on self-amplified spontaneous emission (SASE)

Femtosecond x-ray diffraction from an aerosolized beam of protein nanocrystals [PDF]

, 2017
We demonstrate near-atomic-resolution Bragg diffraction from aerosolized single granulovirus crystals using an x-ray free-electron laser. The form of the aerosol injector is nearly identical to conventional liquid-microjet nozzles, but the x-ray ...

Wavefront sensing at X-ray free-electron lasers. [PDF]

J Synchrotron Radiat, 2019
Here a direct comparison is made between various X-ray wavefront sensing methods with application to optics alignment and focus characterization at X-ray free-electron lasers (XFELs). Focus optimization at XFEL beamlines presents unique challenges due to high peak powers as well as beam pointing instability, meaning that techniques capable of single ...

Free electron laser generation of x-ray Poincaré beams [PDF]

New Journal of Physics, 2020
Abstract An optics-free method is proposed to generate x-ray radiation with spatially variant states of polarization via an afterburner extension to a free electron laser. Control of the polarization in the transverse plane is obtained through the overlap of different coherent transverse light distributions radiated from a bunched ...

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)].

Relativistic x-ray free-electron lasers in the quantum regime [PDF]

, 2012
We present a nonlinear theory for relativistic x-ray free-electron lasers in the quantum regime, using a collective Klein-Gordon (KG) equation (for relativistic electrons), which is coupled with the Maxwell-Poisson equations for the electromagnetic and ...

An X-Ray Regenerative Amplifier Free-Electron Laser Using Diamond Pinhole MIrrors [PDF]

, 2019
Free-electron lasers (FELs) have been built ranging in wavelength from long-wavelength oscillators using partial wave guiding through ultraviolet through hard x-ray FELs that are either seeded or start from noise (SASE).

Stimulated resonant inelastic X-ray scattering in a solid

Communications Physics, 2022
X-ray free electron lasers provide brilliant light with sufficient intensity to strongly drive and probe nonlinear X-ray-matter interactions. Here, spectroscopy of Co/Pd multilayers reveals a nearly one-million-fold enhancement of stimulated resonant ...

Signatures of misalignment in x-ray cavities of cavity-based x-ray free-electron lasers

Physical Review Accelerators and Beams, 2022
Cavity-based x-ray free-electron lasers (CBXFEL) will allow the use of optical cavity feedback to support generation of fully coherent x-rays of high brilliance and stability by electrons in undulators.
