Temperature Sensor Based on Fiber Ring Laser With Sagnac Loop
Jia Shi,Wang Yuye,Degang Xu,Haiwei Zhang,Su Genghua,Liangcheng Duan,Chao Yan,Dexian Yan,Shijie Fu,Jianquan Yao +9 more
TL;DR: In this paper, a temperature sensor based on a fiber ring laser with a reflective Sagnac loop is proposed, which is used as the filter and sensing head to supply high temperature sensitivity.
Journal ArticleDOI
Vanadium dioxide-assisted broadband absorption and linear-to-circular polarization conversion based on a single metasurface design for the terahertz wave.
TL;DR: The proposed multifunctional design combining the broadband absorption and broadband polarization conversion using a single switchable metasurface provides the potential to be used in the fields of advanced research and intelligent applications in the terahertz frequency region.
Journal ArticleDOI
High-average-power, high-repetition-rate tunable terahertz difference frequency generation with GaSe crystal pumped by 2 μm dual-wavelength intracavity KTP optical parametric oscillator
Dexian Yan,Yuye Wang,Degang Xu,Pengxiang Liu,Chao Yan,Jia Shi,Hongxiang Liu,Yixin He,Longhuang Tang,Jianchen Feng,Jianqin Guo,Wei Shi,Kai Zhong,Yuen Hong Tsang,Jianquan Yao +14 more
TL;DR: In this paper, a high-average-power, high-repetition-rate optical terahertz (THz) source based on difference frequency generation (DFG) in the GaSe crystal was demonstrated using a near-degenerate 2-μm intracavity KTP optical parametric oscillator as the pump source.
