Abstract

The invention discloses a high-concentration erbium ion doped tellurium tungstate glass capable of emitting light at mid-infrared 2.7 microns. The glass comprises the following components by molar percent: 58-70% of TeO2, 15-25% of WO3, 0-15% of La2O3, 0-15% of LaF3 and 2-4% of Er2O3. The glass is prepared by adopting an electric furnace melting method of a corundum crucible and a silicon carbide rod. The glass is high in doping concentration of erbium ion, high in infrared transmittance near to the mid-infrared 2.7 microns and good in physicochemical properties; and the stability parameter delta T is not less than 180 DEG C. Strong mid-infrared 2.7 microns fluorescence is obtained under pumping of a laser diode with a wavelength of 980 nm; and the glass is suitable for preparation and application of erbium ion doped special glass and optical fiber materials capable of emitting light at mid-infrared 2.7 microns.

Description

technical field [0001] The invention relates to glass, in particular to high-concentration erbium ion-doped mid-infrared 2.7 μm luminous tellurite tungstate glass. Background technique [0002] The erbium ion 2.7μm laser output is first obtained by doping the crystal with erbium ions. In recent years, 2.7μm output solid-state lasers doped with erbium ions have attracted the attention of researchers because of their important applications in medical surgery, remote sensing detection, bioengineering and military fields. The 3 μm pulsed and continuous laser output was first reported in LiYF4 crystal in 1967. In 1988, Pollack first reported the ZBLAN fluoride fiber doped with erbium ions, due to the Er 3+ : 4 I 11 / 2 → 4 I 13 / 2 Transition, to obtain a laser output with a center wavelength of 2.78 μm and an output energy of 75J. In 2008, Zhu et al. obtained watt-level laser output in ZBLAN fluoride fiber, and then researchers successively obtained nearly 10 watts and 24 wat...
