Using the European XFEL free-electron laser, researchers demonstrate terawatt-scale, attosecond hard X-ray pulses. Ten pulse trains per second, each containing hundreds of pulses at megahertz repetition rates, are achieved. Such short and intense pulses at high repetition rate enable unprecedented dama...

A free electron laser is a source of coherent radiation having the highly desirable characteristics of tunability over a broad range of wavelengths, efficient operation and high power output. In the ultraviolet, such a source could be used for the study of molecular and biological systems, while ...
Free-electron lasers (FELs) are classical lasers that can provide widely tunable, highly intense, ultrashort laser pulses in any part of the spectrum. We present here the basic principles and advantages of FELs, discuss the emergence of self-amplified spontaneous emission FELs as leading candidates...
The European XFEL is the first hard X-ray high-repetition-rate free-electron laser facility. Sakura Pascarelli, Serguei Molodtsov and Thomas Tschentscher, scientific directors of the European XFEL, discuss the challenges that lie ahead before the European XFEL can reach its full potential and ca...
A plasma eigenmode has been employed as a wiggler in a magnetized plasma channel for the generation of laser radiation in a free-electron laser. The short wavelength of the plasma wave allows a higher radiation frequency to be obtained than from conventional wiggler free-electron lasers. The plas...
