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).
