Speedy electrons for brilliant laser light: Research paves the way for compact, inexpensive free-electron lasers

Extremely short, intense light flashes are in high demand to investigate atoms, molecules and new materials. Free-electron lasers (FELs) produce these flashes. But around the world, beam time available at large-scale user facilities is in short supply, and waiting times are long.
