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…
Quantum Control of Molecular Gas Hydrodynamics
Sina Zahedpour, Jared Wahlstrand, Howard Milchberg
We demonstrate that strong impulsive gas heating or heating suppression at standard temperature and pressure can occur from coherent rotational excitation or de-excitation of molec…
Direct measurement of the acoustic waves generated by femtosecond filaments in air
J. K. Wahlstrand, N. Jhajj, E. W. Rosenthal +2
We present direct measurements of the gas acoustic dynamics following interaction of spatial single- and multi-mode 50 fs, 800 nm pulses in air at 10 Hz and 1 kHz repetition rates.…
