We experimentally demonstrate the generation of narrow-bandwidth emissions with excellent coherent properties at similar to 391 and similar to 428 nm from N-2(+) (B-2 Sigma(+)(u)(v' = 0) -> X-2 Sigma(+)(g)(v = 0, 1)) inside a femtosecond filament in air by an orthogonally polarized two-color driver field (i.e. 800 nm laser pulse and its second harmonic). The durations of the coherent emissions at 391 and 428 nm are measured to be similar to 2.4 and similar to 7.8 ps, respectively, both of which are much longer than the duration of the pump and its second harmonic pulses. Furthermore, the measured temporal decay characteristics of the excited molecular systems suggest an 'instantaneous' population inversion mechanism that may be achieved in molecular nitrogen ions at an ultrafast time scale comparable to the 800 nm pump pulse.
