WebHigh-order harmonics (blue) are generated in an argon gas cell. The IR is filtered out by an IR antireflection-coated fused silica plate followed by an aluminum filter. In the application chamber, the harmonic beam is focused by the Wolter optics. The knife is placed around the focus, and the beam is detected by a flat-field spectrometer. WebMar 31, 2024 · The transition metal dichalcogenides have instigated a lot of interest as harmonic generators due to their exceptional nonlinear optical properties. Here, the molybdenum disulfide (MoS2) molecular structures with dopants being in a plasma state are used to demonstrate the generation of intense high-order harmonics. The MoS2 …
WebDec 14, 2024 · In this work, we study the role of these effects in the high-order harmonic spectrum by using the Time-Dependent Density Functional Theory (TDDFT) approach with the Dynamical Mean-Field Theory (DMFT) exchange-correlation kernel. In this approximation, one takes into account the time-resolved on-site electron-electron interactions. WebAug 2, 2024 · High-order harmonic generation (HHG) in solids has entered a new phase of intensive research, with envisioned band-structure mapping on an ultrashort time scale.
