| 摘 要： | 通过对掺Er^3 和Er^3 /Yb^3 共掺光纤激光器的输出功率进行数值模拟发现：高浓度的Er^3 /Yb^3 共掺光纤激光器的最大量子转换效率比同等浓度下的掺Er^3 光纤激光器的最大量子转换效率高出一倍。说明由于Yb^3 的加入，Er^3 /Yb^3 共掺光纤激光器有效地抑制了能量上转换，提高了受激转换效率。

| Abstract: | Numerical analysis of the output power in a Er 3+ doped and a Er 3+ /Yb 3+ codoped fiber has been investigated. The maximum quantum conversion efficiency of the Er 3+ /Yb 3+ codoped fiber with higer Er 3+ Concentration is as twice as that of the Er 3+ doped fiber with similar Er 3+ concentration. This result shows that the energy transfer upconversion in the Er 3+ /Yb 3+ fiber laser is suppressed effectively and excited conversion efficiency for Er 3+ is improved obviously. |
