Abstract

The invention discloses erbium-doped mid-infrared luminescent zirconium zinc-based fluoride glass. Zirconium zinc-based glass which is transparent and better in optical quality is obtained by introducing ZnF2 into erbium-doped mid-infrared luminescent fluorozirconate ZBYAN glass, the infrared transmittance of the zirconium zinc-based glass is kept at a higher level near mid-infrared 2.7 microns, fluorescence emission which is obviously enhanced at mid-infrared 2.7 microns can be obtained under pumping of a laser diode with 980 nm wavelength, and a preparation method is suitable for preparation and application of mid-infrared 2.7 micron laser glass and optical fiber materials.

Description

technical field [0001] The invention belongs to the field of mid-infrared fluoride glass, in particular to an erbium-doped mid-infrared luminescent fluorine-zirconium-zinc-based 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. received widespread attention. The 3μm 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 l...
