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…

Free-space remote sensing of rotation at photon-counting level
Wuhong Zhang, Jingsong Gao, Dongkai Zhang +4
The rotational Doppler effect associated with light's orbital angular momentum (OAM) has been found as a powerful tool to detect rotating bodies. However, this method was only demo…
