英文摘要	In this paper, we experimentally investigate femtosecond laser-induced nitrogen fluorescence emission at different air pressures (0.1Pa-100kPa). The variation of nitrogen molecule (N2) and molecular nitrogen ion (N2+) characteristic fluorescence spectral lines' intensity as a function of air pressure is observed. When the air pressure is between 10Pa and 100kPa, the intensity of fluorescence signals fromN2+ andN2 shows opposite variation as a function of air pressure. We deduce that dissociative recombination is the main pathway for the production of theC3u state ofN2. This research helps elucidate the physical emission mechanism of femtosecond laser-induced nitrogen fluorescence emission. 2021 Author(s).
