Many biologically important molecules change shape when stimulated by UV radiation. Although this property can also be found ...

Using the powerful X-ray Free Electron Laser (FEL) at SLAC National Laboratory in California, the Hamburg team studied how ultrashort pulses interact with nanoparticles. They uncovered a ...

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 ...

To this end, they generated specially prepared, highly intense extreme ultraviolet light pulses using the FERMI free electron laser in Trieste, Italy. The researchers achieved control of the ...

One of the most exciting recent developments is the successful operation of the first next-generation FEL laser — the Linac Coherent Light Source (LCLS) at the Stanford Linear Accelerator Center ...

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 ...
