Laser oscillation of Yb3+:Er3+co-doped phosphosilicate microsphere [Invited]

Abstract: A fiber-taper-microsphere-coupled system was used to research the characteristics of laser oscillation and upconversion luminescence of Yb3+:Er3+ co-doped phosphosilicate (YECP) microspheres. The YECP microspheres were fabricated by melting the end of phosphosilicate filaments. Single- and multimode laser oscillation at 1535-1565 nm within the C-band were obtained. In addition, the output power of the single-mode laser at 1545.5 nm can be as high as 48.98 μW, which was achieved under pump power of 9.63 mW, and… Show more

“…Doping of rare earth ions in the phosphate glass can result in the fabricated phosphate fiber having the attractive characteristics of short length, small volume, high energy conversion efficiency, and low cost for fiber lasers, arousing the interest of many researchers [ 27 , 28 , 29 , 30 , 31 ]. Phosphate glasses have a higher rare earth ion solubility compared with silicate glasses, up to 10 26 ions/m 3 , so they can be doped with high concentrations of rare earth ions to obtain higher gains [ 32 , 33 ].…”

“…Our group has done several researches on laser emission of RE ions doped silica microsphere pumped by 976 nm laser [16][17][18][19]. The light coupled into the microsphere can propagate around the inner orbit surface in the way of total internal reflection with extremely low loss because of the atomic-scale smooth surface, which is called whispering gallery mode (WGM).…”
