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…
Optical design for implementing non-collinear circularly polarized high harmonic generation in an enhancement cavity
Pranshu Dave, Thierry Auguste, Olivier Girard +2
We introduce an original optical cavity design intended to efficiently output-couple extreme ultraviolet (XUV) light produced via cavity-enhanced high harmonic generation (CE-HHG).…
Controlled generation of high-harmonic spatiotemporal optical vortices
Titouan Gadeyne, Vartika Vishnoi, Thierry Ruchon
Spatiotemporal optical vortex (STOV) pulses are puzzling states of light, which see their transverse orbital angular momentum being debated in spite of possessing a topological cha…
