Generation and control of extreme ultraviolet free-space optical skyrmions with high harmonic generation
Yiqi Fang, Yunquan Liu
Optical skyrmion serves as a crucial interface between optics and topology. Recently, it has attracted great interest in linear optics. Here, we theoretically introduce a framework…
Controlling Photon Transverse Orbital Angular Momentum in High Harmonic Generation
Yiqi Fang, Shengyue Lu, Yunquan Liu
High harmonic generation (HHG) with longitudinal optical orbital angular momentum has attracted much attention over the past decade. Here, we present the first study on the HHG wit…
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…
Topologically Protected Strong-Interaction of Photonics with Free Electron
Jing Li, Yiqi Fang, Yunquan Liu
We propose a robust scheme of studying the strong interactions between free electrons and photons using topological photonics. Our study reveals that the topological corner state c…
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…
Roadmap on spatiotemporal light fields
Yijie Shen, Qiwen Zhan, Logan G. Wright +42
Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents the holy grail of the human everlasting pursue of ultrafast information transmission a…
