Outdoor 100-m-scale air waveguides
Andrew Goffin, Gregory Babic, Andrew DeRusha +3
Optical power densities for standoff spectroscopy, remote sensing, directed energy, and free-space optical communications are limited by diffraction and adverse atmospheric conditi…

Topologically constrained high intensity light propagation in air
A. Goffin, L. Railing, G. Babic +1
We experimentally demonstrate how spatiotemporal optical vortices (STOVs) control long-range atmospheric filamentation of intense laser pulses. High-power pulses long enough to ove…
