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…
Backward stimulated radiation from filaments in Nitrogen gas and air pumped by circularly polarized 800 nm femtosecond laser pulses
Sergey Mitryukovskiy, Yi Liu, Pengji Ding +2
We report on strong backward stimulated emission at 337 nm in Nitrogen gas pumped by circularly polarized femtosecond laser pulses at 800 nm. A distinct dependence of the backward…
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…
