Nobel Prize lessons – Electrons in pulses of light

The 2023 Nobel Prize in Physics is awarded for discoveries that gave humanity new tools for exploring the world of electrons inside of atoms and molecules. Pierre Agostini, Ferenc Krausz and Anne L´Huillier have conducted experiments in which they demonstrate a way of producing pulses of light that last for such a short period of time that they are measured in attoseconds. An attosecond is so short that there as many of them in a second as there are seconds in the entire lifetime of the universe.
