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…
Quasi-steady-state air waveguide
A. Goffin, A. Tartaro, H. M. Milchberg
We report the first generation of quasi-steady-state air waveguides capable of guiding high average power laser beams. The guides are produced by high-repetition rate patterned fil…
Optical guiding in 50-meter-scale air waveguides
A. Goffin, I. Larkin, A. Tartaro +1
The distant projection of high peak and average power laser beams in the atmosphere is a longstanding goal with a wide range of applications. Our early proof-of-principle experimen…
Atmospheric aerosol clearing by femtosecond filaments
A. Goffin, J. Griff-McMahon, I. Larkin +1
Atmospheric aerosols, such as water droplets in fog, interfere with laser propagation through scattering and absorption. Femtosecond optical filaments have been shown to clear fogg…
Self-waveguiding of relativistic laser pulses in neutral gas channel
L. Feder, B. Miao, J. E. Shrock +2
We demonstrate that an ultrashort high intensity laser pulse can propagate for hundreds of Rayleigh ranges in a prepared neutral hydrogen channel by generating its own plasma waveg…
