Beneficial from the development of femtosecond laser direct writing technique, the fabrication of Bragg gratings inside a fiber with low photosensitivity like active fiber becomes possible. In this paper, we fabricate erbium-doped fiber Bragg gratings (EDFBGs) using femtosecond laser...

A Cu-1.3Ni-1.2Co-0.7Si-0.3Cr-0.1Mg alloy with high strength and high conductivity was designed and prepared in this work. The effects of multistage thermomechanical treatment on the microstructure and properties of the alloy and its strengthening mechanism were studied. The results showed that a...
