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…
Photoelectronic mapping of spin-orbit interaction of intense light fields
Yiqi Fang, Meng Han, Peipei Ge +6
The interaction between a quantum particle's spin angular momentum and its orbital angular momentum is ubiquitous in nature. In optics, the spin-orbit optical phenomenon is closely…
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…
Electronic quantum coherence induced by strong field molecular ionization
Jinming Chen, Jinping Yao, Haisu Zhang +9
The existence of electronic coherence can fundamentally change the scenario of nonlinear interaction of light with quantum systems such as atoms and molecules, which, however, has…
