| 摘 要： | 基于975nm激发的室温下荧光光谱测量，系统地研究了在新型钠、镱共掺的氟化钙晶体中钠离子的作用机理，分析了掺钠离子浓度与激光阈值的关系，获得了具有最低激光阈值的掺杂浓度优化配比. 激光实验表明对于2%Yb3+离子浓度的氟化钙，掺入3%的钠离子能够获得最低阈值的激光运转，这与理论和荧光分析完全一致. 关键词：镱、钠共掺氟化钙荧光光谱激光阈值

| Abstract: | Basing on measuring the luminescence spectra at room temperature pumped by 975nm light, the action mechanism of Na+ in the novel Yb3+,Na+:CaF2 crystal was systemically investigated. The relation between the concentration of doping Na+ and the laser operation threshold was analyzed. The optimum match concentration for Yb3+,Na+:CaF2 with low laser threshold was obtained. In the experiment, the lowest laser operation threshold at only 70mW of absorbing pumped power for 2%Yb3+, 3%Na+:CaF2 crystal is realized, which is in good agreement with the analysis of luminescence properties. |
