Problems solved by technology

[0003] Er 3+ Ions are passed through 4 I 11 / 2 → 4 I 13 / 2 The transition achieves fluorescence emission near 3 μm, but due to the lower energy level 4 I 13 / 2 upper level 4 I 11 / 2 The lifetime is long, so the effective fluorescence emission near 3 μm wavelength cannot be obtained

Abstract

The invention discloses 3mu m luminous rare-earth ion-doped fluogermanate laser glass and a preparation method thereof. The laser glass comprises the following components: 55 to 65 molar percent of GeO2, 10 to 20 molar percent of BaO / BaF2, 8 to 20 molar percent of Ga2O3, 0 to 8 molar percent of Na2O, 3 to 7 molar percent of La2O3, and 0.1 to 4 molar percent of Re2O3 / ReF3 (Re is a rare-earth element selected from Er, Pr, Yb, Tm, Ho and Nd). Experimental results show that the rare-earth ion-doped fluogermanate laser glass prepared by the method has high infrared transmittance and wide transmission range. The glass can obtain good near 3 mu m fluorescence emission under the action of a laser diode pump of which the wavelength is 980nm, so the glass is suitable for the preparation and application of near 3mu m luminous rare-earth ion-doped special glass and an optical fiber material.

Description

technical field [0001] The invention relates to laser glass, in particular to a 3 μm light-emitting rare earth ion-doped fluorogermanate laser glass and a preparation method thereof. Background technique [0002] For the mid-infrared laser with a wavelength of 3 μm, it has very important application value in the fields of medical surgery, optical communication, environmental pollution detection and analysis, and human eye safety lidar. Er 3+ Ions have been extensively studied as laser-activated ions in various substrates in the 3 μm region. Fluoride and chalcogenide glasses have low phonon energy, so they were favored by researchers in the early research of 3 μm mid-infrared materials. However, the unstable physical and chemical properties of fluorides and the harsh preparation conditions of chalcogenide glasses limit their application prospects. Compared with fluoride, chalcogenide glass, and germanate glass, quartz glass has good physical and chemical properties and a r...
