free-electron laser

[′frē i¦lek‚trän ′lā·zər]
(optics)
A device in which a beam of relativistic electrons passes through a static periodic magnetic field to amplify a superimposed coherent optical wave and thereby produce a powerful beam of coherent light.

Relativistic electron beams from ultraintense laser plasma interactions can be conceived to be compact particle accelerators, inspiring a wide range of applications of unique particle beam and radiation sources as well as downsizing large-scale particle accelerators such as radiation sources of THz, (18) betatron X-ray radiation, (19) X-ray free electron lasers (20,21) and high-energy frontier colliders, (22, 23) some of which have been illustrated in the review article of this Journal.
