Attosecond Light Skyrmion Pulses via High Harmonic Generation
David Marco, Luis Plaja, Carlos Hernández-García
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 be…

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…

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…
