Reacción a "Reactions: Nobel Prize in Physics to Agostini, Krausz and L'Huillier for developing light pulses to study the motion of electrons in matter"

The award of the Nobel Prize in Physics 2023 is undoubtedly excellent news and a source of joy for the national groups working in the field of attophysics, several of which we collaborate with some of those who have received the prize. Lasers are a special light source because of their coherence, i.e. because they emit light in the form of waves with very regular characteristics, light whose structure can be modified at will in laboratories. The laureates developed fundamental contributions that enabled this type of light to be used to control the motion of electrons on scales as short as a few tens of trillionths of a second, technically called the attosecond scale.  
Attosecond technology provides new tools for scientific research, such as flashes of light so brief that we can resolve the motion of electrons in atoms, x-ray laser sources that allow us to probe nanometre structures, and experimental designs that allow us to measure how long processes such as ionisation take - durations so short that they have never been measured before. The three laureates are not only pioneers in this type of technique, but have also developed solid scientific careers, extended over time, and have made an outstanding contribution to the consolidation of atoscience as a new discipline in physics.
