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...
The meaning of FREE-ELECTRON LASER is a laser that can be tuned over a wide range of frequencies and that produces electromagnetic radiation by the motion of electrons moving at relativistic velocities in a magnetic field.

A catalac free electron laser using a rf linac (catalac) which acts as a catalyst to accelerate an electron beam in an initial pass through the catalac and decelerate the electron beam during a second pass through the catalac. During the second pass through the catalac, energy is ...
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...
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...
BEIJING, Jan. 15 (Xinhua) -- Chinese scientists announced they have built a facility that can generate the world's brightest extreme ultraviolet (EUV) free electron laser. The facility in Dalian, a coastal city in northeast China's Liaoning Province, can generate 140 trillion photons per laser...

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...
