High-harmonic generation from solids
WebIn this work, we present our novel approach to explore high-order harmonic generation from solids by introducing a two-color scheme that combines an 80 fs, 3.6 µ m mid-infrared driving field with a 2 ps, 600 µ m single-cycle terahertz dressing field. © 2024 The Author (s) PDF Article Presentation Video More Like This Web23 de fev. de 2024 · High-order harmonic generation of atoms irradiated by an ultrashort laser pulse was calculated by numerically solving the time-dependent Schrödinger equation and the Bohmian trajectory scheme.

Web4 de fev. de 2024 · Introduction. High-order harmonic generation (HHG) has been studied widely in atomic and molecular systems theoretically or experimentally [ 1 – 4 ]. It is a nonlinear phenomenon and has also been used to generate attosecond laser pulses which opens a door to investigate the ultrafast processes [ 5 – 7 ]. WebHigh harmonic generation (HHG) can be induced by focusing an intense laser onto either gas atoms [ 1–5 ], solids [ 6–11 ], or liquids [ 12, 13 ], as sketched in Figure 1. By …
WebWe demonstrate that high-harmonic generation (HHG) in solids dominantly originates from strongly localized surface states through non-perturbative processes. Measurements reveal that HHG from bulk states is suppressed by at least 1-2 orders of magnitude due to the lack of phase matching, when generated perturbatively, or by at least 3-4 orders of
