| 摘 要： | 测量了掺Ｅｒ３＋／Ｙｂ３＋氟铝玻璃的吸收谱，在０．９８μｍ附近，比掺Ｅｒ３＋氟铝玻璃具有明显的吸收增强．用Ｊｕｄｄ－Ｏｆｅｌｔ理论得出了其光谱参量Ωλ（λ＝２，４，６），并计算了有关能级的声子跃迁速率．理论分析及实验结果表明，该材料适合于频率上转换激光的产生

| Abstract: | Absorption spectra and fluorescence in Er 3 /Yb 3 doped fluoroaluminate glass have been measured. According to Judd ofelt theory, the parameters of spectro line strenth have been caculated nonradiative transitions of Er 3 levers have been also analiged. Results show that Er 3 /Yb 3 doped fluoroaluminate glass is a good material for upconversition laser. |
