Self-focused pulse propagation is mediated by spatiotemporal optical vortices
M. S. Le, G. A. Hine, A. Goffin +2
We show that the dynamics of high-intensity laser pulses undergoing self-focused propagation in a nonlinear medium can be understood in terms of the topological constraints imposed…

Spatiotemporal torquing of light
S. W. Hancock, S. Zahedpour, A. Goffin +1
We demonstrate the controlled spatiotemporal transfer of transverse orbital angular momentum (OAM) to electromagnetic waves: the spatiotemporal torquing of light. This is a radical…
