Optical air waveguides in strong turbulence
A. Goffin, G. I. Babić, H. M. Milchberg
Filament-generated air waveguides offer a route to low loss long-distance optical transport, but their viability in atmospheric turbulence has remained uncertain. Here, we demonstr…
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…
Characterization of Spatiotemporal Overlap of Femtosecond Lasers and Electron Beam With Ce:YAG Screens
Kevin Eckrosh, Sean Tilton, Lucas Malin +12
Interactions between short laser pulses and electron bunches determine a wide range of accelerator applications. Finding spatiotemporal overlap between few-micron-sized optical and…
