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…
Compact, folded multi-pass cells for energy scaling of post-compression
Arthur Schönberg, Supriya Rajhans, Esmerando Escoto +12
Combining high peak and high average power has long been a key challenge of ultrafast laser technology, crucial for applications such as laser-plasma acceleration and strong-field…
The influence of final state interactions in attosecond photoelectron interferometry
Sizuo Luo, Robin Weissenbilder, Hugo Laurell +14
Fano resonances are ubiquitous phenomena appearing in many fields of physics, e.g. atomic or molecular photoionization, or electron transport in quantum dots. Recently, attosecond…
Highly versatile, two-color setup for high-order harmonic generation using spatial light modulators
Ann-Kathrin Raab, Marvin Schmoll, Emma R. Simpson +7
We present a novel, interferometric, two-color, high-order harmonic generation setup, based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each int…
