Using high-intensity lasers, researchers have taken an important step toward miniaturization of particle accelerators by demonstrating free-electron laser amplification at extreme ultraviolet ...

For the first time, researchers have demonstrated that a laser-plasma accelerator can reliably drive a free-electron laser for more than eight hours. Published in Physical Review Accelerators and ...

Proof-of-concept experimental setup used to generate an extreme ultraviolet (XUV) free-electron laser (FEL) driven by a laser wakefield acceleration (LWFA) electron beam. An intense laser pulse, ...
