Description

technical field [0001] The invention belongs to the field of mid-infrared fluoride glass, in particular to an erbium-doped mid-infrared luminescent chlorofluorophosphorus glass. Background technique [0002] In recent years, erbium-doped solid-state lasers with 3 μm output have very important application value in remote sensing, ranging, environmental detection, bioengineering and medical treatment, as well as pumping sources for new mid-infrared band lasers. aroused widespread concern. The 3 μm laser output was first obtained by doping the crystal with erbium ions. However, the preparation and processing of single crystals with large size and excellent performance is difficult and expensive, while rare earth ion-doped laser glass has a mature preparation process, and large-size products with high optical uniformity can be obtained, and the rare earth ion concentration and glass composition It can be adjusted in a large range, which is conducive to improving its laser perf...
