Plasma dynamics of a laser filamentation-guided spark
Guillaume Point, Leonid Arantchouk, Jérôme Carbonnel +2
We investigate experimentally the plasma dynamics of a centimeter-scale, laser filamentation-guided spark discharge. Using electrical and optical diagnostics to study monopolar dis…
Laser beam self-symmetrization in air in the multifilamentation regime
Carles Milian, Vytautas Jukna, Arnaud Couairon +6
We show experimental and numerical evidence of spontaneous self-symmetrization of focused laser beams experiencing multi-filamentation in air. The symmetrization effect is observed…
Generation of long-lived underdense channels using femtosecond filamentation in air
Guillaume Point, Carles Milián, Arnaud Couairon +2
Using femtosecond laser pulses at 800 and 400 nm, we characterize the formation of underdense channels in air generated by laser filamentation at the millijoule energy level by mea…
Superfilamentation in air
Guillaume Point, Yohann Brelet, Aurélien Houard +6
The interaction between a large number of laser filaments brought together using weak external focusing leads to the emergence of few filamentary structures reminiscent of standard…
Externally seeded backward lasing radiation from femtosecond laser filament in nitrogen gas
Pengji Ding, Sergey Mitryukovskiy, Aurélien Houard +3
Recently, S. Mitryukovskiy et al. presented experimental evidence showing that backward stimulated radiation at 337 nm can be obtained from plasma filaments in nitrogen gas pumped…
Effect of input pulse chirp on nonlinear energy deposition and plasma excitation in water
C. Milián, A. Jarnac, Y. Brelet +4
We analyze numerically and experimentally the effect of the input pulse chirp on the nonlinear energy deposition from J fs-pulses at nm to water. Numerical results are…
