Multi-level perspective on high-order harmonic generation in solids
Mengxi Wu, Kenneth J. Schafer, Mette B. Gaarde
We investigate high-order harmonic generation in a solid, modeled as a multi-level system dressed by a strong infrared laser field. We show that the cutoff energies and the relativ…
Spatially and spectrally resolved quantum path interference with chirped driving pulses
Stefanos Carlström, Jana Preclíková, Eleonora Lorek +7
We measure spectrally and spatially resolved high-order harmonics generated in argon using chirped multi-cycle laser pulses. Using a stable, high-repetition rate laser we observe d…
Role of Excited States In High-order Harmonic Generation
Samuel Beaulieu, Seth Camp, Dominique Descamps +8
We investigate the role of excited states in High-order Harmonic Generation by studying the spectral, spatial and temporal characteristics of the radiation produced near the ioniza…
Attosecond Transient Absorption in Dense Gases: Exploring the Interplay between Resonant Pulse Propagation and Laser-Induced Line Shape Control
Chen-Ting Liao, Seth Camp, Kenneth J. Schafer +2
We investigate the evolution of extreme ultraviolet (XUV) spectral lineshapes in an optically-thick helium gas under near-infrared (IR) perturbation. In our experimental and theore…
