Near-focus intensity evolution of spatiotemporal optical vortex pulses and consequences for their nonlinear upconversion
Titouan Gadeyne, Vartika Vishnoi, Thierry Ruchon
Spatiotemporal optical vortex (STOV) laser pulses are attracting attention for their puzzling transverse orbital angular momentum (OAM) and propagation properties, which could dete…
