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…
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.…
