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…

Parity-mixing interference in laser-assisted photoionization

N. Ouahioune, D. Hoff, P. K. Maroju +5

Photoionization of atoms by high-order harmonics in the presence of a laser may lead to quantum interference from which information about the photoionization dynamics or the light…

Subcycle phase matching effects in short attosecond pulse trains

N. Ouahioune, R. Martín-Hernández, D. Hoff +8

Attosecond pulses produced by High-order Harmonic Generation (HHG) in gases driven by intense laser fields have become a cornerstone technique for probing ultrafast electronic moti…

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…

Photoionization time delays probe electron correlations

Mingxuan Li, Huiyong Wang, Rezvan Tahouri +16

The photoelectric effect, explained by Einstein in 1905, is often regarded as a one-electron phenomenon. However, in multi-electron systems, the interaction of the escaping electro…

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…
