摘要:

实验对比研究了Ga2O5、TeO2、GeO2、WO3、Nb2O5和Bi2O5金属氧化物的掺入对氟磷激光玻璃的光谱和激光性能的影响。结果表明, TeO2、GeO2和Ga2O5的加入增大了Yb3+的吸收和发射截面; 其中, 掺有TeO2的氟磷玻璃的Yb3+吸收和发射截面最大, 分别达到了1.95 pm2和0.85 pm2。Ga2O5、Nb2O5和GeO2的加入对玻璃激光性能的提高具有极大的帮助; 其中, 在掺有Ga2O5的氟磷玻璃中激光参数SFL值最大, 为1.237。同时发现, 在TeO2和GeO2掺杂氟磷玻璃中也存在严重的Yb3+荧光俘获现象, 大大减弱了其激光性能。

Abstract:

Effects of the different metal oxides added with Ga2O5, TeO2, GeO2, WO3, Nb2O5 and Bi2O5 respectively on the spectroscopic and lasing properties of Yb3+-doped fluorophosphate glasses were comparatively investigated. Results show that the additions of TeO2, GeO2 and Ga2O5 can increase the absorption and emission cross sections of Yb3+-ions. Among the three glasses above, the TeO2-doped glass has the largest parameters up to 1.95 pm2 and 0.85 pm2, respectively. Meanwhile, the dopants of Ga2O5, Nb2O5 and 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 TeO2 and GeO2, respectively, which strongly lessens the lasing properties.

Key words: fluorophosphate glasses, metal oxides, absorption cross section, emission cross section, lasing property
