| 测试了Ho：YAG和Ho：YLF晶体的吸收话和荧光谱，计算Ho~（3＋）离子的振子强度参数f_JJ~t［c］，辐射跃迁几率地A_J，J'荧光辐射寿命τJ［c］，并与实验测得的荧光辐射寿命τJ［e］及振子强度的实验值f_J［e］比较。应用跃迁速率方程计算得出对应2．1μm的荧光强度最大的掺杂离子Ho~（3＋）的最佳浓度分别为～2．5％和～1％左右。讨论了YAG和YLF作为芬Ho~（3＋）的基质晶体优点。 |
| 英文摘要: |
| The absorption and fluorescence spectra of Ho3+inos were measured. The oscil lator strength f[c],the probabilities of radiative transitions A J,J,fluorescence lifetime [c] of Ho3+ ions in YAG and YLF crystals were calculated on the basis of Judd-ofelt theory,and were compared on fluorescence lifetime [c]obetaind from experiments and experimentel values f J .J[c]of oscillator strength. The optimum doped relative concentrations of Ho 3+ ions in these crystals were calculated from transmition rate-equations as-2. 5% and -1 % respectively. The advantages of YAG and YLF crystals as laser host crystals of Ho3+ ions were discussed. |
