Abstract

The invention relates to intermediate infrared 2.7 mum luminous erbium ion-doped gallium germanium bismuthate glass. The molar percentage composition range of the glass is shown as follows: 43-48 percent of Bi2O3, 22-27 percent of GeO2, 17-23 percent of Ga2O3, 0-10 percent of MgO, 0-10 percent of Na2O and 0.2-3 percent of Er2O3. The glass is prepared by adopting a corundum crucible and silicon carbide rod electric furnace melting method. The glass has high infrared transmittance nearby intermediate infrared 2.7 mum and excellent physical and chemical property, and the stability parameter delta t is more than or equal to 160 DEG C; and strong intermediate infrared 2.7 mum fluorescent light can be obtained under the pumping of a laser diode with a wavelength of 980 nm. The glass is suitable for the preparation and the application of intermediate infrared 2.7 mum luminous erbium ion-doped heavy metal oxide glass and optical fiber materials.

Description

technical field [0001] The invention relates to a mid-infrared 2.7 μm luminescent erbium ion doped germanium gallium bismuthate glass. Background technique [0002] In recent years, erbium ion-doped mid-infrared 3μm output solid-state lasers have attracted people's attention because their wavelength is very close to the absorption peak of water. Therefore, the erbium-doped solid-state laser with 3 μm output has 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 3 μm pulsed and continuous laser output was first reported in LiYF4 crystal in 1967. At present, there are many researches at home and abroad on obtaining 3 μm output through rare earth doped crystals, but the crystals are difficult to prepare due to large size and low rare earth doping concentration, which limits its application. The rare earth-doped glass fiber can well avoid th...
