A nitrogen gas pumped by near-infrared femtosecond pulses gives rise to a coherent emission at 391.4 nm due to transitions between ionic levels. For the first time, we experimentally analyze the temporal evolution of the populations of N$_2^+$ levels involved in this lasing process. To visualize this dynamics, we measure the transmission of a high harmonics source through N$_2^+$.
