Generation of High-order Harmonic Spatiotemporal and Spatiospectral Optical Vortices | CU Experts

Overview

Spatiotemporal (STOV) and spatiospectral (SSOV) optical vortices are unique structured light tools for exploring ultrafast laser-matter interactions. We theoretically and experimentally study the high-topological charge extreme-ultraviolet/attosecond regime STOV and SSOV generation through high-order harmonic generation.
