Description
High-order harmonic generation, a non-linear process resulting from the interaction of an intense and ultrashort laser field with a dilute medium (atoms or molecules in the gas phase), can be used as a secondary source of XUV photons. At the same time, informations about the process itself are intrinsically encoded in this spectrum (amplitude, phase, polarisation). The study of these characteristics is known as harmonic spectroscopy. In this talk, I will present a selection of some high harmonic spectroscopy studies based on various observables and carried out over the last few years at CELIA.
