Nitrogen air lasing induced by multiple filaments array
文献摘要：
Air lasing emission by launching intense ultrafast laser pulses in atmosphere has recently attracted increasing interest in the ultrafast laser science and atmospheric science fields,especially for remote sensing techniques.We demon-strated the fluorescence emissions at 337 nm,357 nm and 391 nm induced by multiple filaments using four kinds of step phase plates.Our results have indicated that the fluorescence signal has been amplified as it propagates along the filament through amplified spontaneous emission(ASE),and the fluorescence intensity is also enhanced in the back-ward direction via multiple filaments.Furthermore,the gain coefficient through ASE is increased with the number of filaments.
