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…
Air hydrodynamics of the ultrafast laser-triggered spark gap
E. W. Rosenthal, I. Larkin, A. Goffin +4
We present space and time resolved measurements of the air hydrodynamics induced by ultrafast laser pulse excitation of the air gap between two electrodes at high potential differe…
Molecular Quantum Wakes for Clearing Fog
Malte C. Schroeder, Ilia Larkin, Thomas Produit +3
High intensity laser filamentation in air has recently demonstrated that, through plasma generation and its associated shockwave, fog can be cleared around the beam, leaving an opt…
Spatio-temporal optical vortices
N. Jhajj, I. Larkin, E. W. Rosenthal +3
We present the first experimental evidence, supported by theory and simulation, of spatiotemporal optical vortices (STOVs). Quantized STOVs are a fundamental element of the nonline…
Sensitivity of propagation and energy deposition in femtosecond filamentation to the nonlinear refractive index
E. W. Rosenthal, J. P. Palastro, N. Jhajj +3
The axial dependence of femtosecond filamentation in air is measured under conditions of varying laser pulsewidth, energy, and focusing f-number. Filaments are characterized by the…
Collection of remote optical signals by air waveguides
E. W. Rosenthal, N. Jhajj, J. K. Wahlstrand +1
Collection of weak signals from remote locations is the primary goal and the primary hurdle of optical stand-off detection schemes. Typically, the measured signal is enhanced using…
