Femtosecond laser filamentation is a unique nonlinear optical phenomenon when high-
power ultrafast laser propagation in all transparent optical media. During filamentation in the …

Recent studies have demonstrated that femtosecond laser pulses have high potential in
application to environmental science. Because of the properties of ultrafast, broadband and …

Filamentation of ultra-short TW-class lasers recently opened new perspectives in
atmospheric research. Laser filaments are self-sustained light structures of 0.1–1 mm in …

Abstract 428 nm forward lasing action was observed from a femtosecond laser filament in air
created by Ti: sapphire laser pulses. The 800 nm femtosecond laser filament not only …

Backward angular distributions of the sodium fluorescence in NaCl aerosols induced by
femtosecond laser filamentation in air with a distance of 10 m are measured. The recorded …

We experimentally demonstrate the generation of lasing action in the laminar ethanol/air
flame on an alcohol burner array using femtosecond laser filament excitation. By probing the …

We experimentally demonstrate ultrafast dynamic of generation of the 337-nm nitrogen laser
by injecting an external seed pulse into a femtosecond laser filament pumped by a circularly …

Air lasing is a concept that refers to remote no-cavity (mirrorless) optical amplification in
ambient air with the air constituents as the gain media. Due to the high potential of air lasing …

We report on experimental realization of impulsive rotational Raman scattering from neutral
nitrogen molecules in a femtosecond laser filament using an intense self-induced white-light …
