In a striking glimpse into extreme physics, scientists have captured the split-second chaos that unfolds when powerful laser ...

The understanding of complex many-body dynamics in laser-driven polyatomic molecules is crucial for any attempt to steer chemical reactions by means of intense light fields. Ultrashort and intense ...

Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement ...

Researchers have announced an important step in the development of a next-gen technology for making X-ray free-electron laser pulses brighter and more stable: They used precisely aligned mirrors made ...
