Increased bandwidth and fluctuations are hurdles on the path towards generating intense fully coherent X-ray free-electron laser output. A recent experiment at FERMI Trieste demonstrated that these difficulties can be overcome by an approach called echo-enabled harmonic generation.doi:10.1038/s41566-019...

In the wave picture, the beam is a coherent laser mode and so can be imbued with typical structured light features. On the other hand, the ray picture opens new DoFs to be controlled, for example, the amount of rays, their directions and positions, and so on, so as to extend the ...

X-ray opticsCRYSTALSX-ray lasersX-ray scatteringThe wavefront preservation of coherent X-ray free-electron laser beams is pushing the requirement on the quality and performance of X-ray optics to an unprecedented level. The Strehl ratio can be used to quantify this requirement. In this paper,...
Quantum Free Electron Lasers (QFELs) could emit monochromatic, coherent short-wavelength radiation due to the discrete nature of the electron-radiation momentum exchange during photon emission. A SASE-QFEL may offer the possibility to produce intense, coherent 纬-rays via harmonic generation. The ...
Rivers are an important component of the global carbon cycle and contribute to atmospheric carbon exchange disproportionately to their total surface area. Largely, this is because rivers efficiently mobilize, transport and metabolize terrigenous organic
Driving high-intensity ultrashort laser pulses into overdense plasmas tends to produce electron beams with higher charge number at lower peak energy compared to those from underdense plasmas in laser wakefield acceleration. This interaction between relativistic laser pulses and solids has been studied in...
