The world's shortest laser pulse

ETH researchers succeeded in shortening the pulse duration of an X‑ray laser to only 43 attoseconds. With a time resolution in the range of a few quintillionths of a second, they are now able for the first time to observe the movement of electrons during chemical reactions in slow motion.
Starting from an infrared laser, the researchers generate a soft X-ray laser pulse with a very large spectral bandwidth and a record-short pulse duration. As a result, various elements including phosphorus and sulphur can be directly observed by exciting their inner-shell electrons. Both elements are present in biomolecules, and it is now possible to observe them with unprecedented time resolution.
