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…
Underwater acoustic wave generation by filamentation of terawatt ultrashort laser pulses
Vytautas Jukna, Amelie Jarnac, Carles Milián +9
Acoustic signals generated by filamentation of ultrashort TW laser pulses in water are characterized experimentally. Measurements reveal a strong influence of input pulse duration…
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…
Two-color interferometer for the study of laser filamentation triggered electric discharges in air
Guillaume Point, Yohann Brelet, Leonid Arantchouk +4
We present a space and time resolved interferometric plasma diagnostic for use on plasmas where neutral-bound electron contribution to the refractive index cannot be neglected. By…
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…
