A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

X-ray free-electron lasers (x-ray FELs) give us for the first time the possibility to explore
structures and dynamical processes of atomic and molecular systems at the angstrom …

Abstract The recently commissioned Linac Coherent Light Source is an X-ray free-electron
laser at the SLAC National Accelerator Laboratory. It produces coherent soft and hard X-rays …

High-gain free-electron lasers (FELs) are being developed as extremely bright sources for a
next-generation x-ray facility. In this paper, we review the basic theory of the start-up, the …

Due to the interaction of physics and astrophysics we are witnessing in these years a
splendid synthesis of theoretical, experimental and observational results originating from …

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 …

The brightness of x-ray sources has been increased one to ten billion times by x-ray free-
electron lasers (XFELs) that generate high intensity coherent photon pulses at wavelengths …

We report the first experimental results on a high-gain harmonic-generation (HGHG) free-
electron laser (FEL) operating in the ultraviolet. An 800 nm seed from a Ti: sapphire laser …

The successful lasing at the SLAC National Accelerator Laboratory of the Linear Coherent
Light Source (LCLS), the first X-ray free-electron laser (X-ray FEL), in the wavelength range …

With the scientific successes of the soft X-ray FLASH facility in Germany and the recent
spectacular commissioning of the Linac Coherent Light Source at SLAC, free electron lasers …
