specific Embodiment approach

[0026] 1. Weigh the high-purity raw materials according to the following molar percentages, and mix them thoroughly in the grinding bowl; 1,1.5,2,3,4,6,8,10)

[0027] 2. Put the mixture in a platinum crucible with a lid, melt it in a glove box high-temperature furnace at 930°C, then place the molten glass on a preheated brass mold, and place it in an annealing furnace at 270°C for annealing. Relieve the stress generated in the glass to obtain the final glass sample.

Abstract

The invention provides Ho<3+>-doped fluorine-aluminum glass. Fluorescence emission of a 2.4 [mu]m middle-infrared band under 638nm laser pumping excitation, and the molar percentage of the concentration of raw materials and doped ions of a glass matrix is as follows: 30AlF3-15BaF2-(20-x)YF3-25PbF2-10MgF2-xHoF3 (x = 0.2, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10). The ion-doped glass prepared by the invention is high in transparency, high in luminous efficiency, excellent in chemical stability and simple in preparation process, and can be used as a 2.4 [mu]m middle-infrared band optical fiber laser gain medium. The research method and the research result have important reference value and guiding significance for further research of mid-infrared glass materials and mid-infrared lasers.

Description

technical field [0001] The present invention relates to a kind of fluorine aluminum glass, in particular to a kind of Ho 3+ Doped fluoroaluminum glass. Background technique [0002] Mid-infrared (2-20μm) lasers are located in the absorption band of vibrational energy levels of many gas molecules and organic molecules, the so-called "molecular fingerprint region", so mid-infrared lasers are used in disease diagnosis, trace gas detection, molecular spectroscopy and other fields It has important application prospects. In addition, there are three transparent "windows" in the space atmosphere, which are 2-2.7 μm, 3-5 μm and 8-13 μm, respectively. Therefore, mid-infrared lasers also have important application potential in remote remote sensing, space communication, and military fields. At present, the laser technology in the visible and near-infrared bands has matured, while the mid-infrared laser, especially the mid-infrared laser in the 3 μm and above bands, has developed ver...
