Pulse-Duration Control of Subcycle Multiband Electron Dynamics Extends the High-Harmonic Cutoff in a Light-Driven Insulator
Hortense Allegre, Simon V. B. Jensen, Joseph J. Broughton +7
We demonstrate pathway-selective control of extreme-ultraviolet high-harmonic generation by jointly tuning laser pulse duration ( - fs) and intensity ( - TW/cm$^2…
Extreme Ultraviolet High-Harmonic Interferometry of Excitation-Induced Bandgap Dynamics in Solids
Lisa-Marie Koll, Simon Vendelbo Bylling Jensen, Pieter J. van Essen +9
Interferometry is a fundamental technique in physics, enabling precise measurements through the interference of waves. High-harmonic generation (HHG) in solids has emerged as a pow…
Intra- and intercycle analysis of intraband high-order harmonic generation
Asbjørn Tornøe Andersen, Simon Vendelbo Bylling Jensen, Lars Bojer Madsen
We study intraband high-order harmonic generation arising from a band-gap material driven by a linearly polarized laser field. We factorize the intraband high-order harmonic-genera…
