| 摘 要： | 通过求解（Ｃｅ，Ｅｒ）：ＹＡＧ和Ｅｒ：ＹＡＧ的能级跃迁速率方程，讨论了Ｃｅ＾３＋对Ｅｒ＾３＋离子的敏化作用。表明掺Ｃｅ＾３＋可增强Ｅｒ＾３＋离子１．６６μｍ波长的激光强度，但仅改变了１．６６μｍ波长激光粒子数反转，即Ｎ２（＾４Ｉ１２／２）〉Ｎ１（＾４Ｉ１５／２）与Ｅｒ＾３＋离子浓度的关系。

| Abstract: | The sensitive effect of cerium to erbium ions has been analyzed by solving the rate quations of level transition in Ce, Er: YAG and Er: YAG crystals. It is shown that this effect increases the laser intensity at wavelengths both 1.66 and 2.94 μm, but only changes the relation between the population inversion of 4I 13/2 and 4I 15/2 levels and the concentration of Er 3+ ions. |

| Keywords: | sensitization effect population inversion concentration of Er 3+ ions. |
