An X-ray free-electron laser (XFEL) is an X-ray produced by a beam of free electrons that have been accelerated almost to the speed of light. XFELs produce laser beams with exceedingly high peak power intensity, which makes ...

Scientists have used a powerful X-ray laser to heat water from room temperature to 100,000 degrees Celsius in less than a 10th of a picosecond (millionth of a millionth of a second). The experimental setup, which can be seen ...

Every powerful X-ray pulse produced for experiments at a next-generation laser project, now under construction, will start with a "spark" – a burst of electrons emitted when a pulse of ultraviolet light strikes a 1-millimeter-wide ...
