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…

Attosecond vortex pulse trains
Alba de las Heras, David Schmidt, Julio San Román +5
The landscape of ultrafast structured light pulses has recently evolved driven by the capability of high-order harmonic generation (HHG) to up-convert orbital angular momentum (OAM…

Robust isolated attosecond pulse generation with self-compressed sub-cycle drivers from hollow capillary fibers
Marina Fernández Galán, Javier Serrano, Enrique Conejero Jarque +8
High-order harmonic generation (HHG) arising from the non-perturbative interaction of intense light fields with matter constitutes a well-established tabletop source of coherent ex…
