Abstract

The temporal evolution of intensity of N₂ 337 nm and N₂⁺ 391.2 nm lines is compared with modeling results for filament plasma produced by tightly focused femtosecond laser pulse (0.9 mJ, 48 fs). Model correctly predicts enhanced emission of 1⁺ system, higher intensity of O I 777.4 nm line and dynamics of excited states density.
