Space-time wave packets

M Yessenov, LA Hall, KL Schepler… - Advances in Optics and …, 2022 - opg.optica.org
Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Free-space propagation of spatiotemporal optical vortices

SW Hancock, S Zahedpour, A Goffin, HM Milchberg - Optica, 2019 - opg.optica.org
Spatiotemporal optical vortices (STOVs) are a new type of optical orbital angular momentum
(OAM) with optical phase circulation in space–time. In prior work [Phys. Rev. X. 6, 031037 …

Spatiotemporal torquing of light

SW Hancock, S Zahedpour, A Goffin, HM Milchberg - Physical Review X, 2024 - APS
We demonstrate the controlled spatiotemporal transfer of transverse orbital angular
momentum (OAM) to electromagnetic waves: the spatiotemporal torquing of light. This is a …

Transverse orbital angular momentum of amplitude-perturbed fields

SW Hancock, N Tripathi, MS Le, A Goffin… - arxiv preprint arxiv …, 2024 - arxiv.org
We review and clarify several recent theoretical approaches to transverse orbital angular
momentum (tOAM). We then apply our tOAM theory [Phys. Rev. Lett. 127, 193901 (2021)] to …

Transient-grating single-shot supercontinuum spectral interferometry (TG-SSSI)

SW Hancock, S Zahedpour, HM Milchberg - arxiv preprint arxiv …, 2020 - arxiv.org
We present a technique for the single-shot measurement of the space-and time-resolved
spatiotemporal amplitude and phase of an ultrashort laser pulse. The method, transient …
