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 ...

Attosecond X-ray free electron laser [PDF]

EPJ Web of Conferences, 2013
For a real, meaningful pump-probe experiment with attosecond temporal resolution, an isolated attosecond pulse is in demand. In this vein we report the generation of an isolated ~ 148 attosecond pulse duration radiation pulse at 0.1 angstrom wavelength using current enhanced self-amplified spontaneous emission free electron laser.

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 ...

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 ...

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).
