Journal ArticleDOI
Regulation of gold nanoparticles for the rare earth luminescence enhancement based on nanoporous silica glass
Yunxiu Ma,Zhangru Chen,Yingbo Chu,Yu Yang,Yongguang Liu,Haiqing Li,Jinggang Peng,Nengli Dai,Jinyan Li,Luyun Yang +9 more
TL;DR: In this article, a silica composite system with rare earth ions and gold nanoparticles was fabricated based on nanoporous silica glass and the formation and optical properties of the systems were controlled by the nanoparticles doping concentration and heat treatment.
Journal ArticleDOI
Active radiation hardening of Tm-doped silica fiber based on pump bleaching.
Yingbin Xing,Nan Zhao,Lei Liao,Yibo Wang,Haiqing Li,Jinggang Peng,Lvyun Yang,Nengli Dai,Jinyan Li +8 more
TL;DR: It is found that the recovery time and radiation induce absorption are positively associated with doses, however, the fiber slope efficiency and the fiber cladding absorption spectra after irradiation and bleaching are both negatively correlated with doses.
Journal ArticleDOI
Investigation of cerium influence on photo-darkening and photo-bleaching in Yb-doped fibers
Nan Zhao,Yibo Wang,Jiaming Li,Chaoping Liu,Jinggang Peng,Haiqing Li,Nengli Dai,Luyun Yang,Jinyan Li +8 more
TL;DR: In this paper, photo-bleaching is considered as a convenient way to mitigate the photo-darkening (PD) in Yb-doped fibers, and it is shown that more than 30% PD loss was achieved after 180min pumping of 793-nm LD.
Journal ArticleDOI
Yb 3+ heavily doped photonic crystal fiber lasers prepared by the glass phase-separation technology
Yingbo Chu,Yu Yang,Xiongwei Hu,Zhangru Chen,Yunxiu Ma,Yongguang Liu,Yibo Wang,Lei Liao,Yinbin Xing,Haiqing Li,Jinggagn Peng,Nengli Dai,Jinyan Li,Luyun Yang +13 more
TL;DR: A Yb3+ heavily doped photonic crystal fiber with 30 μm core diameter manufactured for the first time by an alternative technique provides an alternative means of preparing large active silica rods with high doping levels and excellent material homogeneity for large mode area fibers with complex designs.
Journal ArticleDOI
Effects of Al2O3 composition on the near-infrared emission in Bi-doped and Yb–Bi-codoped silicate glasses for broadband optical amplification
TL;DR: In this article, the effect of Al 2 O 3 composition on the near-infrared (NIR) emission and energy transfer between Yb 3+ and Bi n+ (Bi NIR emission centers) was investigated.
