几种重金属氧化物和GeO2的加入对掺Yb3+氟磷玻璃的光谱和激光性能的影响
Influences of the Dopants of Several Heavy Metal Oxides and GeO2 on Spectro-scopic and Lasing Properties of Yb3+-doped Fluorophosphate Glasses
摘要
Abstract
Effects of the different metal oxides added withGa2O5, TeO2, GeO2, WO3, Nb2O5 and Bi2O5respectively on the spectroscopic and lasing properties of Yb3+-doped fluorophosphate glasses were comparatively investigated. Re-sults show that the additions ofTeO2, GeO2 and Ga2O5 can increase the absorption and emission cross sections of Yb3+-ions. Among the three glasses above, theTeO2-doped glass has the largest parameters up to 1.95 pm2and 0.85 pm2, respectively. Meanwhile, the dopants of Ga2O5, Nb2O5and GeO2 are beneficial to the improvement of lasing properties in fluorophosphate glasses. Laser parameters (SFL) of fluorophosphate glass doped with Ga2O5 is 1.237, the largest of all the glasses. Moreover, serious fluorescence trapping of Yb3+ is found in fluorophosphate glasses doped with TeO2and GeO2, re-spectively, which strongly lessens the lasing properties.关键词
