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…
Attosecond Light Skyrmion Pulses via High Harmonic Generation
David Marco, Luis Plaja, Carlos Hernández-GarcÃa
Paraxial light skyrmions are topological configurations that map a spatial domain of the field onto the full Poincaré sphere of polarization states. While optical skyrmions have b…
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…
Isolated attosecond spatio-temporal optical vortices: Interplay between the topological charge and orbital angular momentum scaling in high harmonic generation
Rodrigo Martin-Hernandez, Luis Plaja, Carlos Hernandez-Garcia +1
The propagation properties and the nature of the transverse orbital angular momentum (t-OAM) of spatiotemporal optical vortices (STOVs) open new scenarios in high-harmonic generati…
Extreme-ultraviolet spatiotemporal vortices via high harmonic generation
Rodrigo Martin-Hernandez, Guan Gui, Luis Plaja +5
Spatiotemporal optical vortices (STOV) are space-time structured light pulses with a unique topology that couples spatial and temporal domains and carry transverse orbital angular…
Circularly polarized high harmonic beams carrying self-torque or time-dependent orbital angular momentum
Alba de las Heras, Julio San Román, Javier Serrano +2
In the rapidly evolving field of structured light, the self-torque has been recently defined as an intrinsic property of light beams carrying time-dependent orbital angular momentu…
