Abstract
High-harmonic generation (HHG) is a nonlinear process that converts intense infrared (IR) radiation into high-frequency light [1,2]. It can be understood as a sequence of three steps: (1) tunnel ionization of an atom or a molecule induced by the strong IR field, (2) laser-driven acceleration of the electron in the continuum, and (3) recombination with the parent ion resulting in the emission of harmonic light. Since there is a well-defined relationship between the duration of the electron excursion and the energy released during recombination, the harmonic spectrum provides snapshots of the laser-induced dynamics in the ion [3]. Very recently, the application of elliptically polarized fields has allowed to probe molecular chirality with sub-femtosecond time resolution [4], opening new directions in high-harmonic spectroscopy [5].
