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…
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…
Optical Magnetic Field Enhancement using Ultrafast Azimuthally Polarized Laser Beams and Tailored Metallic Nanoantennas
Rodrigo Martín-Hernández, Lorenz Grünewald, Luis Sánchez-Tejerina +4
Structured light provides unique opportunities to spatially tailor the electromagnetic field of laser beams. This includes the possibility of a sub-wavelength spatial separation of…
