The characterization of amplified spontaneous emission (ASE) from this newly fabricated single-mode Er3+-doped tellurite fibers is also presented. When pumped at 980 nm, a very broad erbium ASE around 1.53 μm was observed. The variations of ASE with fiber length and pumping power are measured and discussed. The output of 2 mW from Er3+-doped tellurite fiber ASE source was obtained under the pump power of 660 mW.展开更多

By energy transferring and multiphoton process, the visible and ultraviolet radiation occurs when the Er<sup>3+</sup>-Yb<sup>3+</sup>-doped fiber is pumped by the laser at 980-nm band. Further researches on the mechanism of the fluorescence of Er<sup>3+</sup>-Yb<sup>3+</sup>-doped silica fiber pumped by Ti: A1<sub>2</sub>O<sub>3</sub> tunable laser at 980-nm band are helpful展开更多
