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…
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…
