Influence of the laser pulse duration in high-order harmonic generation
Saga Westerberg, Melvin Redon, Ann-Kathrin Raab +10
High-order harmonic generation (HHG) in gases has been studied for almost 40 years in many different conditions, varying the laser wavelength, intensity, focusing geometry, target…

Energy scaling in a compact bulk multi-pass cell enabled by Laguerre-Gaussian single-vortex beams
Victor Koltalo, Saga Westerberg, Melvin Redon +5
We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex () beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-…

XUV yield optimization of two-color high-order harmonic generation in gases
Ann-Kathrin Raab, Melvin Redon, Sylvianne Roscam Abbing +7
We perform an experimental two-color high-order harmonic generation study in argon with the fundamental of an ytterbium ultrashort pulse laser and its second harmonic. The intensit…
