摘　　要：A new type of germanate-tellurite glass with doped Tm^(3+) ions is synthesized and its 1.8 μm emission properties have been studied for its application as a laser material. The Judd–Ofelt intensity parameters, emission cross section, absorption cross section, and gain coefficient of Tm^(3+) ions are calculated and analyzed. Germanate-tellurite glass with 1.0 mol% Tm_(2)O_(3) possesses the highest spontaneous transition probability (423.4 s^(-1)) and the largest calculated emission cross section (6.91×10^(-21) cm^(2)) at 1.8 μm corresponding to the ^(3)F_(4)→^(3)H_(6) transition. The good 1.8 μm emission performance suggests that this glass may become an attractive host for developing solid state lasers operating in the mid-infrared.
