That X-Ray Laser, called Linac Coherent Light Source (LCLS) gives researchers a look at the world like no other. The best minds from around the world apply to work with the laser to better ...

For self-seeding, the undulator is split into two pieces, the first of which is used to make an X-ray laser. A monochromator is then placed between the two undulators to select a narrow band ...

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 ...

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 of light, to oscillate in a long ...

The Lawrence Livermore National Laboratory (LLNL) has created the brightest X-ray source to date, by directing the laser of the National Ignition Facility (NIF) onto ultra-light metal foams. Reported ...

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in atoms, molecules, and solids. An attosecond—equivalent to a billionth ...

Terahertz radiation (THz), electromagnetic radiation with frequencies ranging from 0.1 and 10 THz, is central to the ...
