Ultrashort pulsed laser atmospheric filament properties and microwave radiation inferred from S-band guided wave interaction and self-emission
Edward. L. Ruden, James. E. Wymer, Jennifer. A. Elle +4
The electrical conductivity of the plasma filament left behind by an ultrashort pulsed laser (USPL) optical pulse after it is geometrically then self-focused in air via the Ker…
Generation of Radio Frequency Radiation by Femtosecond Filaments
Travis Garrett, Jennifer Elle, Michael White +9
Recent experiments have shown that femtosecond filamentation plasmas generate ultra-broadband radio frequency radiation (RF). We show that a combination of plasma dynamics is respo…
Single-cycle THz signal accompanying laser wake in photoionized plasmas and plasma channels
S. Y. Kalmykov, A. Englesbe, J. Elle +1
Photoionization by a femtosecond, terawatt laser pulse generates a plasma column in a neutral ambient gas. Velocity of electrons, pushed by the laser ponderomotive force along the…
Picosecond laser filamentation in air
Andreas Schmitt-Sody, Heiko G. Kurz, L. Bergé +2
The propagation of intense picosecond laser pulses in air in the presence of strong nonlinear self-action effects and air ionization is investigated experimentally and numerically.…
