| 英文摘要 | to investigate the relatively unexplored 1.2 mu m region, we identified a near-infrared emission at around 1.23 mu m from er3+/pr3+-codoped water-free fluorotellurite glass with a composition of 60teo(2)-30znf(2)-10naf (tznf60, mol. %). under the condition of pumping with the 488 nm optical parametric oscillator (opo) laser system, the directly measured lifetime (tau(f)) at 1.23 mu m in er/pr-codoped fluorotellurite glasses is about 111.2 mu s, much longer than that of er-doped fluorotellurite glass (80.1 mu s). the stimulated emission cross section (sigma(em)) and quantum efficiency (eta) for er3+:s-4(3/2) -> i-4(11/2) transition are greatly enhanced when appropriate pr3+ ions are incorporated. these advances arise partially from the absence of the hydroxyl (oh) group and low phonon energy with the addition of a large amount of fluorides into oxide-based host glasses. with high quantum efficiency (56.2%) and a large stimulated cross section (4.03 x 10(-21) cm(2)), er3+/pr3+-codoped tznf60 glass is regarded as promising material for the development of optical amplification and laser operation at the relatively unexplored 1.2 mu m region.
