The 2023 Nobel Prize in Physics recognized Pierre Agostini for pioneering experimental techniques that generate attosecond pulses of light to observe electron dynamics in matter. Born in 1941 in Tunis, this French physicist transformed strong-field laser science through his development of methods to characterize pulses lasting only billionths of a billionth of a second.
Academic Foundations in France
Agostini completed his secondary schooling at the Prytanée National Militaire, earning his baccalauréat in 1959. He pursued higher education at Aix-Marseille University, where he secured a licence d'enseignement in 1961, followed by a diplôme d'études approfondies in 1962. By 1968, he finished his doctoral research focused on multilayer dielectric filters, specifically analyzing the properties of antimony trioxide thin films in ultraviolet applications.

Take the IQ test →Research at CEA Saclay
In 1969, Agostini joined the CEA Saclay research center, an institution where he remained for over three decades. Working within the laboratory of Gérard Mainfray and Claude Manus, he concentrated on multiphoton ionization phenomena. A significant breakthrough occurred in 1979, when his team successfully observed above-threshold ionization for the first time using xenon gas. This observation marked a crucial step in understanding the behavior of atoms under intense laser radiation.
Attosecond Science and RABBITT
During his final years at CEA Saclay, Agostini collaborated with researchers from the Dutch Foundation for Fundamental Research on Matter to manipulate ultrashort light pulses. In 2001, he helped create a pulse train with durations of 250 attoseconds. To measure these intervals, he developed the Reconstruction of Attosecond Beating By Interference of Two-photon Transitions (RABBITT) technique. This method utilized the interference of infrared light with ultraviolet pulses to precisely characterize pulse repetition rates and lengths.
Transition to the United States
Agostini served as a visiting scientist at the Brookhaven National Laboratory from 2002 until 2004, working within the group led by Louis F. DiMauro. In 2005, he accepted a professorship at the Ohio State University. He continued his research in collaboration with DiMauro at this new institution until he transitioned to emeritus status in 2018. His sustained contributions to spectroscopy and nonlinear optics earned him election as a Fellow of the Optical Society in 2008.
