| 摘 要： | 在理论分析的基础上，具体讨论了Fe质量分数小于10-4对1 053 nm处光吸收损耗和Nd3+无辐射跃迁几率的影响规律，发现Fe在1 053 nm处的光吸收损耗和Nd3+无辐射跃迁能量转移都与Fe质量分数成平方关系增长， Fe对1 053 nm光吸收的影响较大而Fe与Nd3+之间的能量转移不足50 Hz。这对生产过程中Fe含量的控制有重要指导意义。

| Abstract: | Based on theoretic analysis on experimental data, the changes of the optical absorption and Nd3+ non-radiative transition probability caused by Fe concentration in N31 glass are discussed in detail. The optical loss at 1 053 nm and Nd3+ non-radiative energy losses increase quadratically with Fe concentration below 10-4. It is found that the optical absorption loss at 1 053 nm increases rapidly with increasing Fe concentration. However, Nd3+ non-radiative energy losses are less than 50 Hz. It is an important way to improve the laser performance by decreasing Fe concentration in melting process. |
