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…
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…
Lasing of ambient air with microjoule pulse energy pumped by a multi terawatt IR femtosecond laser
Guillaume Point, Yi Liu, Yohann Brelet +4
We report on the lasing action of atmospheric air pumped by an 800 nm femtosecond laser pulse with peak power up to 4 TW. Lasing emission at 428 nm increases rapidly over a small r…
