With intensities 108–1010 times greater than other laboratory sources, X-ray free-electron
lasers are currently opening up new frontiers across many areas of science. In this 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 …

We propose to use the mechanism of an echo effect previously observed in hadron
accelerators for up-frequency conversion of density modulation in an electron beam. We …

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 …

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 …

X-ray free-electron lasers (XFELs) are cutting-edge research tools that produce almost fully
coherent radiation with high power and short-pulse length with applications in multiple …

The generation of attosecond, highbrightness x-ray pulses is a matter of great interest given
their applications in the study of ultra-fast processes. In recent years, the production of x-ray …

A novel scheme to compress the radiation pulse in x-ray free electron lasers is proposed not
only to shorten the pulse length but also to enhance the peak power of the radiation, by …

The successful operation of x-ray free-electron lasers (FELs), like the Linac Coherent Light
Source or the Free-Electron Laser in Hamburg (FLASH), makes unprecedented research on …

A method is proposed to generate trains of few-cycle x-ray pulses from a free-electron laser
(FEL) amplifier via a compact “afterburner” extension consisting of several few-period …
