Near single-cycle pulse generation using a cascaded all-bulk multi-pass cell compression system
Saga Westerberg, Gaspard Beaufort, Sara Rushe Palacios +5
We experimentally demonstrate the generation of sub-two-cycle optical pulses using a cascaded post-compression scheme based on two bulk multi-pass cells. Starting from 220 fs, 100…
Compact, intense attosecond sources driven by hollow Gaussian beams
Rodrigo MartÃn-Hernández, Melvin Redon, Ann-Kathrin Raab +9
High-order harmonic generation (HHG) enables the up-conversion of intense infrared or visible femtosecond laser pulses into extreme-ultraviolet attosecond pulses. However, the high…
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-…
