Transverse orbital angular momentum of amplitude-perturbed fields
S. W. Hancock, N. Tripathi, M. S. Le +2
We measure the change in transverse orbital angular momentum (tOAM) per photon, delta L_y, applied to an optical pulse by a pure amplitude perturbation. The results are in excellen…

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…
