| 摘 要： | 计算了ＹＡＧ晶体中Ｔｍ＾３＋离子辐射跃迁几率Ａｉｊ，无辐射跃迁几率Ｗｉｊ，交叉弛豫几率Ｐ，荧光寿命τｉ和荧光分支比βｉｊ等荧光特征参量，并利用这些值及跃迁速率方程讨论了＾３Ｆ４能级荧光强度与掺杂浓度的关系，得出当激发光的泵浦速率从１０＾２～１０＾６ｓ＾－１时，Ｔｍ＾３＋离子的最佳相对浓度Ｘｏｐ在４．９～６．４％之间。

| Abstract: | The fluorescence charecteristic parameters of Tm3+ ions in Tm: YAG crystals for radiative transition probabilities Aij, non-radiative probabilities Wij, cross relaxation probability P, fluorescence lifetimes τ and fluorescence branching rations βij, et al. are caculated. The dependence of the population of 3F4 level on dopant concentration x is studied. The optimum relative concentration xop of Tm3+ ions of 4. 9～ 6. 4 % is obtained,when the range of probablility of excited level by pump light are 102～ 106 sec-1. |
