| 摘 要： | The mid-infrared(MIR) luminescent properties of Dy~(3+) ions in a new chalcohalide glass host, Ga_2S_3–Sb_2S_3–CsI,are investigated; and the suitability of the doped glass for MIR fiber lasers is evaluated. The Dy~(3+)-doped chalcohalide glasses exhibit good thermal stability and intense MIR emissions around 2.96 μm and 4.41 μm. These emissions show quantum efficiencies(η) as high as ~60%, and have relatively large stimulated emission cross sections(σem). The low phonon energy(~307 cm~(-1)) of the host glass accounts for the intense MIR emissions, as well as the high η. These favorable thermal and emission properties make the Dy~(3+)-doped Ga_2S_3–Sb_2S_3–CsI glasses promising materials for MIR fiber amplifiers or lasers.
