英文摘要	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.
