Abstract :
A new type of germanate-tellurite glass with Tm3+ ions doped was synthesized and its 1.8μm emission properties have been studied for its application as laser materials. The Judd-Ofelt intensity parameters, emission cross section, and absorption cross section of Tm3+ ions were calculated and analyzed. Germanate-tellurite glass with 1.0 mol% Tm2O3 possesses the highest spontaneous transition probability (423.4s-1) and the largest calculated emission cross section (6.91×10-21cm2) at 1.8μm. The good 1.8μm emission performance suggests that this glass may become an attractive host for developing mid-infrared solid state lasers.
