Linear accelerator-based free-electron lasers (FELs) are the leading source of fully coherent
X-rays with ultra-high peak powers and ultra-short pulse lengths. Current X-ray FEL facilities …

Generation of intense, fully coherent radiation with wide spectral coverage has been a long-
standing challenge for laser technologies. Several techniques have been developed in …

High-resolution X-ray spectroscopy in the sub-nanosecond to femtosecond time range
requires ultrashort X-ray pulses and a spectral X-ray flux considerably larger than that …

Accelerator-based light sources such as storage rings and free-electron lasers use
relativistic electron beams to produce intense radiation over a wide spectral range for …

Steady-state microbunching (SSMB) storage rings are an appealing option for high-power
extreme ultraviolet (EUV) light sources. In this paper, we propose a generalized longitudinal …

The Shanghai soft X-ray Free-Electron Laser facility (SXFEL) is being developed in two
steps; the SXFEL test facility (SXFEL-TF), and the SXFEL user facility (SXFEL-UF). The …

The fourth generation of synchrotron radiation sources, commonly referred to as the Free
Electron Laser (FEL), provides an intense source of brilliant X-ray beams enabling the …

To steer and track electron motion in atoms, molecules, and nanostructures, light pulses with
attosecond duration and high repetition rate are required. In this paper, we use the angular …

Generation of ultrashort coherent radiation pulses in the extreme ultraviolet (EUV) and x-ray
regime is of remarkable interest in the synchrotron radiation user community. In this work, a …

The echo-enabled harmonic generation (EEHG) scheme holds promising prospects for
efficiently generating intense coherent radiation at very high harmonics of a conventional …
