Attosecond pulse leads to highest molecular level probe resolution

Devising a source of ultra-fast X-ray pulsating in the attosecond range is no mean feat. It enables physicists to probe dynamic processes in matter with unprecedented time resolution. Now, a team of physicists has exploited an optical phenomenon, opening the door to creating high-order oscillations in existing light sources and a beam source pulsating in an ultra-fast manner to reach the attosecond range.
