Controlling the polarization of nitrogen ion lasing
Jingsong Gao, Xiang Zhang, Yang Wang +6
Air lasing provides a promising technique to remotely produce coherent radiation in the atmosphere and attracts continuous attention. However, the polarization properties of N2+ la…
Amplification of light pulses with orbital angular momentum (OAM) in nitrogen ions lasing
Haicheng Mei, Jingsong Gao, Kailu Wang +6
Nitrogen ions pumped by intense femtosecond laser pulses give rise to optical amplification in the ultraviolet range. Here, we demonstrated that a seed light pulse carrying orbital…
Structured air lasing of N2+
Jingsong Gao, Xiang Zhang, Yang Wang +8
Structured light has attracted great interest in scientific and technical fields. Here, we demonstrate the first generation of structured air lasing in N2+ driven by 800 nm femtose…
Multiple-Photon Resonance Enabled Quantum Interference in Emission Spectroscopy of N_2^+
Xiang Zhang, Qi Lu, Yalei Zhu +13
Quantum interference occurs frequently in the interaction of laser radiation with materials, leading to a series of fascinating effects such as lasing without inversion, electromag…
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…
Population Redistribution among Multiple Electronic States of Molecular Nitrogen Ions in Strong Laser Fields
Jinping Yao, Shicheng Jiang, Wei Chu +11
We carry out a combined theoretical and experimental investigation on the population distributions in the ground and excited states of tunnel ionized N2 molecules at various driver…
