What are X-Ray Free-Electron Lasers? X-ray free-electron lasers (XFELs) are a revolutionary type of X-ray source that produce ultra-short, highly intense pulses of X-rays. Unlike conventional X-ray ...

and the European XFEL project 4 (2014). The hard X-ray FEL has come of age. A free-electron laser is not like other lasers. It works by forcing a beam of electrons, travelling at nearly the speed ...

Free-electron lasers create coherent light by constantly accelerating a beam of electrons. Free-electron lasers are particularly useful because they can produce radiation with a short-wavelength ...
