Cascade-Gain-Switching for Generating 3.5-$\mu$ m Nanosecond Pulses From Monolithic Fiber Lasers
Autor: Jianlong Yang, Haizhe Zhong, Shuaiyi Zhang, Yulong Tang, Dianyuan Fan
Publikováno v: IEEE Photonics Journal, Vol 10, Iss 5, Pp 1-12 (2018)
We propose a novel laser configuration that can output 3.5-μm nanosecond laser pulses based on a simple and monolithic fiber structure. Cascade-gain-switching (CGS) converts the wavelength of nanosecond pulses from 1.55 to 3.5 μm by two successive

Theoretical Characterization of the Ultra-Broadband Gain Spectra at $\sim$1600–2100 nm From Thulium-Doped Fiber Amplifiers
Autor: Jianlong Yang, Haizhe Zhong, Shuaiyi Zhang, Dianyuan Fan
Publikováno v: IEEE Photonics Journal, Vol 8, Iss 6, Pp 1-10 (2016)
In this paper, we present the theoretical modeling and characterization of the gain spectra at ~1600-2100 nm from thulium-doped fiber amplifiers (TDFAs) for the first time. Our theoretical model was validated through the comparison with the experimen

Sn2+ doping-induced large extra vibrational energy of an excited state for efficient blue emission in Cs2SnCl6:Bi
Autor: Shaofan Fang, Jinbo Huang, Huixia Li, Jingheng Nie, Zexiang Liu, Feier Fang, Haizhe Zhong
Publikováno v: Materials Advances. 4:2365-2371
Sn2+ and Bi3+ co-doped Cs2SnCl6 was achieved by using SnCl2 as the precursor. Sn2+ increases the extra vibrational energy of the excited state through more localized excitons, and thus greatly improves the radiative transition efficiency.
