Anne L'Huillier is a Swedish/French researcher in the  attosecond science. During the first part of her career, she worked at the Commissariat à l'Energie Atomique, in Saclay, France, first as a PhD student until 1986, then as a permanent researcher until 1995.  She was awarded the Nobel Prize in Physics 2023 together with Pierre Agostini and Ferenc Krausz for “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”.

       When an intense laser interacts with a gas of atoms, high-order harmonics are generated. In the time domain, this radiation forms a train of extremely short light pulses, of the order of 100 attoseconds. Attosecond pulses allow the study of the dynamics of electrons in atoms and molecules, using pump-probe techniques. This presentation will highlight some of the key steps of the field of attosecond science.
