Abstract

The invention provides an erbium ion doped intermediate infrared luminous fluorine tellurate glass. In terms of mol percentage, the glass comprises the following components by mole percent: 43-53 % of ZrF4, 18-22 % of CaF2, 3-5 % of YF3, 2-4 % of AlF3, 18-22 % of NaF, 0-5 % of TeO2, 0-5 % of GeO2, 0-5 % of Bi2O3 and 2-8 % of ErF3. The glass is prepared by using a covered platinum crucible and a silicon carbide rod electric furnace melting method. According to the invention, after heavy metal oxide is introduced, a fluoride glass is still transparent without crystallization, the infrared transmission rate of the glass is 85 % near intermediate infrared 2.7 microns, the heat stability of the glass is improved and the chemical stability of the glass is also improved; under laser diode pumping with wavelength of 980 nm, obviously enhanced intermediate infrared 2.7 microns fluorescence can be obtained; and the erbium ion doped intermediate infrared luminous fluorine tellurate glass provided by the invention is suitable for preparing and using erbium ion doped special glass and optical fiber materials which are luminous at intermediate infrared wave band of 2.7 microns.

Description

technical field [0001] The invention relates to luminescent glass, in particular to fluorine tellurite glass doped with erbium ions and emitting mid-infrared light. Background technique [0002] In recent years, erbium ion-doped 3μm output solid-state lasers have attracted people's attention because their wavelength is very close to the absorption peak of water. Erbium-doped 3μm output solid-state lasers 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. The 3μm laser output was first obtained by doping the crystal with erbium ions. The 3 μm pulsed and continuous laser output was first reported in LiYF4 crystal in 1967. In 1980, Bagdasarov reported that a 100mJ laser output in the 3μm band was obtained in Er-doped yttrium aluminum garnet (YAG) crystal. At present, there are many researches at home and abroad on obtaining 3 μm output th...
