X-ray free-electron lasers produce pulses of light that are exceptionally bright, making them powerful tools for studying ultrafast chemical reactions, biological processes, or probing the structure ...
The Attosecond Science group at the Center for Free-Electron Laser Science has developed a novel light source capable of producing extremely short pulses for the investigation of UV-induced molecular ...
Left: A standard SwissFEL pulse. Middle: Researchers created tuneable frequency combs in the X-rays pulses from SwissFEL. The lines in the spectrum show the ‘teeth’ of the comb, where the light is ...
At SwissFEL, PSI researchers demonstrated a technique known as mode-locking, which allows fully coherent, ultrashort X-ray pulses to be produced. In the photo, several undulator modules are visible ...
