Pierre Agostini is a French experimental physicist and Emeritus professor at the Ohio State University in the United States, known for his pioneering work in strong-field laser physics and attosecond science. He is especially known for the observation of above-threshold ionization and the invention of the reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) technique for characterization of attosecond light pulses. He was jointly awarded the 2023 Nobel Prize in Physics. The Nobel Prize in Physics 2023, announced October 3, 2023. 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”.
