Spontaneous optical skyrmion generation by frequency doubling in underdense plasmas
Marcos G. Barriopedro, Eduardo Oliva, Miguel A. Porras
Optical skyrmions have been widely explored in recent years. Among them, Stokes skyrmions require sophisticated wave engineering or photonic devices for their generation. We show t…

Scaling law from orbital angular momentum conservation in harmonic and high-order harmonic generation driven by spatiotemporal light fields
Miguel A. Porras, Marcos G. Barriopedro, Rodrigo MartÃn-Hernández
Nonlinear photon upconversion processes driven by diverse forms of structured light are receiving increasing attention. In harmonic and high-order harmonic generation (HG and HHG)…
