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…

Roadmap on Attosecond Science

Rocio Borrego Varillas, Pierre Agostini, Fernando Ardana-Lamas +108

Twenty-five years have passed since the first experimental demonstration of attosecond pulses, marking the advent of our ability to resolve and control electron motion in real time…

Towards direct nonlinear compression of energetic sub-nanosecond pulses to the ultrafast regime

Gaspard Beaufort, Nayla Jimenez, Gunnar Arisholm +5

Applications of terawatt-class lasers can enormously benefit from pulse trains with kHz repetition rates. The associated unprecedented combinations of peak and average powers requi…

Compact, intense attosecond sources driven by hollow Gaussian beams

Rodrigo Martín-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…
