Generation of a few femtoseconds pulses in seeded FELs using a seed laser with small transverse size

Short-wavelength free-electron laser sources and science: a review

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The aim is to provide newcomers to the area with insights into: the basic physics of FELs, the qualities of the…

Generation, Acceleration and Measurement of Attosecond Electron Beams from Laser-Plasma Accelerators

Accelerator-based light sources are extremely useful machines for investigating matter on a microscopic level, yet their capability for time-resolved research is limited by the femtosecond-scale…
