| 摘要 | Using physical and chemical dehydration technique and traditional melting and quenching method, we fabricated a group of Er/Pr-codoped water-free fluorotellurite glasses with composition of 60TeO(2)-30ZnF(2)-10NaF (TZNF60, mol%). The lifetime tau(f) of I-4(11/2) -> I-4(13/2) transition, directly measured under the excitation by an optical parametric oscillator (OPO) laser system at 978 nm, in Er/Pr codoped fluorotellurite glasses is 1.37-1.55 ms, longer than that of Er-doped tellurite oxide (215 mu s) and Er-doped fluorotellurite glasses (1.07 ms). The introduction of Pr3+ ions into Er-doped system increases the emission intensity at 2.71 mu m (Er: I-4(11/2) -> I-4(13/2)) and emission cross section as well. These advances partially arise from the absence of OH groups and low phonon energy with the addition of large amount of fluorides into oxide-based host glasses. With the high quantum efficiency and large figure of merit, Er/Pr-TZNF60 glass can be potentially a promising material for the development of mid-infrared fiber lasers at around 2.7 mu m.
