Controlled free-induction decay in the extreme ultraviolet
Samuel Bengtsson, Esben W. Larsen, David Kroon +8
Coherent sources of attosecond extreme ultraviolet (XUV) radiation present many challenges if their full potential is to be realized. While many applications benefit from the broad…
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…
Phase metrology with multi-cycle two-colour pulses
Carl Leon Michael Petersson, Stefanos Carlström, Kenneth J Schafer +1
Strong-field phenomena driven by an intense infrared (IR) laser depend on during what part of the field cycle they are initiated. By changing the sub-cycle character of the laser e…
