X-ray free-electron lasers (XFELs) provide femtosecond X-ray pulses with a narrow energy bandwidth and unprecedented brightness. Ultrafast physical and chemical dynamics, initiated with a site-specific X-ray pulse, can be explored using XFELs with a second ultrashort X-ray probe pulse. However...
X-ray free-electron lasers (XFELs) are unique tools that are making possible time-resolved measurements of structural and electronic dynamics at the quantum spatial and temporal scales. Jonathan Marangos discusses the transformative scientific potential of this capability but also stresses the importance...
X-ray free-electron lasers (XFELs) open a new era of X-ray based research by generating extremely intense X-ray flashes. To further improve the spectrum brightness, a self-seeding FEL scheme has been developed and demonstrated experimentally. As the next step, new-generation FELs with high ...
X-ray free electron lasers (XFELs) deliver intense, coherent, femtosecond X-ray laser pulses. They are opening new research fields of studying ultrafast electronic and structural dynamics in various forms of matter and interaction of intense and short X-ray pulses with matter. For such studies,...

X-ray free-electron lasers (XFELs) generate very powerful X-ray pulses with durations of femtoseconds, i.e., quadrillionths of a second. Machines of this type, currently operating at only a few locations in the world, are used, amongst others, to analyze structure of matter by means of...
About a decade ago, linear-accelerator based X-ray free-electron lasers (XFELs) emerged to offer novel research potential in a variety of scientific fields [3]. These X-ray sources generate ultra-short, highly intense, coherent X-ray pulses, delivering in femtoseconds the same number of phot...
