Reconstruction Of Attosecond Beating By Interference Of Two-photon Transitions
Reconstruction of attosecond beating by interference of two-photon transitions, more commonly known as RABBITT or RABBIT for short, is a widely used technique for obtaining the relative phase and amplitude of attosecond pulses. This technique involves the interference of two-photon interband transitions in solids. It is especially suited for diagnostics on the temporal structure of XUV pulses. The reconstruction of attosecond beating by interference of two-photon transitions is a valuable tool for studying ultrafast processes in materials and can provide insight into the dynamics of electrons in solids. History RABBITT was invented by Pierre Agostini, Harm Geert Muller and colleagues in 2001. References {{reflist Experimental physics Ultrafast spectroscopy ...

Pierre Agostini
Pierre Agostini (; born 23 July 1941) is a French experimental physicist and Emeritus professor at the Ohio State University, 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. Education and career Pierre Agostini was born in Tunis, in the French protectorate of Tunisia, in 1941. He obtained his ''baccalauréat'' at the Prytanée national militaire school in 1959 in La Flèche, France. Agostini studied physics at Aix-Marseille University, where he subsequently received a B.Ed. degree (''licence d'enseignement'') in physics in 1961, and a M.A.S. degree (''diplôme d'études approfondies'') in 1962. In 1968 he completed a doctoral degree th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experimental Physics
Experimental physics is the category of disciplines and sub-disciplines in the field of physics that are concerned with the observation of physical phenomena and experiments. Methods vary from discipline to discipline, from simple experiments and observations, such as Galileo's experiments, to more complicated ones, such as the Large Hadron Collider. Overview Experimental physics encompasses all the disciplines of physics that are concerned with data acquisition, data-acquisition methods, and the detailed conceptualization (beyond simple thought experiments) and realization of laboratory experiments. It is often contrasted with theoretical physics, which is more concerned with predicting and explaining the physical behaviour of nature than the acquisition of empirical data. Although experimental and theoretical physics are concerned with different aspects of nature, they both share the same goal of understanding it and have a symbiotic relationship. The former provides data a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
