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…
Second harmonic generation of spatiotemporal optical vortices and conservation of orbital angular momentum
S. W. Hancock, S. Zahedpour, H. M. Milchberg
Spatiotemporal optical vortices (STOVs) are a new type of intrinsic optical orbital angular momentum (OAM) structure in which the OAM vector is orthogonal to the propagation direct…
Transient-grating single-shot supercontinuum spectral interferometry (TG-SSSI)
S. W. Hancock, S. Zahedpour, H. M. Milchberg
We present a technique for the single-shot measurement of the space- and time-resolved spatiotemporal amplitude and phase of an ultrashort laser pulse. The method, transient-gratin…
Full path single-shot imaging of femtosecond pulse collapse in air turbulence
I. Larkin, J. Griff-McMahon, A. Schweinsberg +3
In a single shot, we measure the full propagation path, including the evolution to pulse collapse, of a high power femtosecond laser pulse propagating in air. This technique enable…
Ultrashort infrared 2.5-11μm pulses: spatiotemporal profiles and absolute nonlinear response of air constituents
S. Zahedpour, S. W. Hancock, H. M. Milchberg
We measure the detailed spatiotemporal profiles of femtosecond laser pulses in the infrared wavelength range λ=2.5-11μm, and the absolute nonlinear response of major air constituen…
