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…
Soft x-rays with Orbital Angular Momentum for resonant scattering experiments at the SOLEIL synchrotron
Pietro Carrara, Franck Fortuna, Renaud Delaunay +15
The paper presents a comprehensive description of a new setup implemented and commissioned at the SEXTANTS beamline of the SOLEIL synchrotron for absorption and scattering experime…
Optical spin-orbit interaction induced by magnetic textures
Martin Luttmann, Mauro Fanciulli, Pietro Carrara +2
Contrary to the optical spin angular momentum (SAM), the role played by the orbital angular momentum (OAM) of light in magneto-optics remains largely unexplored. However, the SAM a…
Energy and photon centroids of spatiotemporal light pulses and consequences for their intrinsic orbital angular momentum
Titouan Gadeyne, Thierry Ruchon
An ongoing debate surrounding the intrinsic transverse orbital angular momentum (OAM) attributed to spatiotemporal optical vortex (STOV) light pulses has raised the energy and phot…
Few-cycle optical vortices for strong field physics
Matthieu Guer, Martin Luttmann, Jean-François Hergott +3
We report on the generation of optical vortices with few-cycle pulse durations, 500J per pulse, at a repetition rate of 1 kHz. To do so, a 25 fs laser beam at 800 nm is shaped w…
High-resolution ptychographic imaging at a seeded free-electron laser source using OAM beams
M. Pancaldi, F. Guzzi, C. S. Bevis +21
Electromagnetic waves possessing orbital angular momentum (OAM) are powerful tools for applications in optical communications, new quantum technologies and optical tweezers. Recent…
Attosecond dynamics through a Fano resonance: Monitoring the birth of a photoelectron
V. Gruson, L. Barreau, Á. Jiménez-Galan +11
Amplitude and phase of wavepackets encode the dynamics of quantum systems. However, the rapidity of electron dynamics on the attosecond timescale has precluded their complete measu…
