The Nobel Prize in Physics for 2023 has been bestowed upon Pierre Agostini from Ohio State University (USA), Ferenc Krausz from Max Planck Institute of Quantum Optics (Garching) and Ludwig-Maximilians-Universität München (Germany), and Anne L’Huillier from Lund University (Sweden). They have been honored for their pioneering work in developing experimental techniques which culminated in the generation of incredibly brief attosecond light pulses, enabling the study of electron dynamics in matter. Attosecond Physics has unveiled new insights into the world of electrons, providing the opportunity to gain a deeper understanding of electrondriven mechanisms. In this presentation, we will delve into the major milestones in the history of lasers, beginning with its invention in 1960, progressing through the development of nanosecond, picosecond, and femtosecond laser systems, and ultimately to the creation of attosecond light pulses. Furthermore, we will explore potential applications of attosecond light pulses.
