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 …

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 crystallography has been central to the development of many fields of science over the
past century. It has now matured to a point that as long as good-quality crystals are …

Free-electron lasers produce extremely brief, coherent, and bright laser-like photon pulses
that allow to image matter at atomic resolution and at timescales faster than the …

More than a century ago, the term 'virus' was introduced to describe infectious agents that
are invisible by light microscopy and capable of passing through sterilizing filters. In addition …

The development and application of the free-electron X-ray laser (XFEL) to structure and
dynamics in biology since its inception in 2009 are reviewed. The research opportunities …

X-ray free-electron lasers provide femtosecond-duration pulses of hard X-rays with a peak
brightness approximately one billion times greater than is available at synchrotron radiation …

Intense femtosecond x-ray pulses from free-electron laser sources allow the imaging of
individual particles in a single shot. Early experiments at the Linac Coherent Light Source …

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 …

Phase retrieval is a long-standing problem in imaging when only the intensity of the
wavefield can be recorded. Coherent diffraction imaging is a lensless technique that uses …
