Attophysics Science

In 2023 the Swedish Academy awarded the Nobel Prize for Physics to Pierre Agostini, Ferenc Krausz and Anne L'Huillier: “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”. The history of this Nobel begins in 1987 when L'Huiller discovered that from the interaction between a noble gas and a beam of laser light, light waves at different wavelengths are produced, thus laying the theoretical foundations for the creation of pulses very short lights. At the beginning of the 2000s, the research groups led by Agostini and Krausz, in parallel and with different experimental set-ups, managed to produce a laser capable of emitting light pulses of 250 and 650 attoseconds respectively, also managing to measure its length.
