Coherent control of superradiance from nitrogen ions pumped with femtosecond pulses
An Zhang, Qingqing Liang, Mingwei Lei +8
Singly ionized nitrogen molecules in ambient air pumped by near-infrared femtosecond laser give rise to superradiant emission. Here we demonstrate coherent control of this superrad…

Lasing without population inversion in air
André Mysyrowicz, Rostyslav Danylo, Pengji Ding +8
A cavity-free laser in the sky could lead to revolutionary improvements in optical remote sensing for atmospheric science. Abundant in air, nitrogen molecules are prime candidates…
