Joint SLAC and Stanford Physics special colloquium: Attosecond pulse trains, RABBITT and applications
Dr. Pierre Agostini, The Ohio State University, Emeritus Professor, and 2023 Physics Nobel Prize Laureate
-
Abstract: Attosecond pulse trains (APT) emerged from high harmonics (Anne L’Huillier et al, 1987) and their spectral phase determination by RABBITT (Pierre-Marie Paul et al, 2001). Although the record of the shortest pulse of 43 attoseconds belongs to the technique of isolated attosecond pulse (IAP) [1], APT and RABBITT have been extremely popular over the last 20 years. In this talk I will briefly review the physics involved in both as well as some applications at Ohio-State including photoionization delays, and the recent timing of non-sequential double ionization [2]. In conclusion I will evoke the advent of zeptoseconds in photoionization delays [3] and the future of attosecond science high-power IAP at free-electron laser [4].
