摘要
为了确定将来实验中参数，对975nm激光抽运采用1064nm种子脉冲放大方案实现的掺镱双包层脉冲光纤激光器进行了数值计算，分析了暂态情况下在光纤中的反转粒子数密度、抽运光强度的分布，讨论了输出能量和输入种子脉冲能量的关系。利用这些结果可以解决实验中光纤长度、抽运光、种子源的选择，以及与输出功率大小的关系等问题。
Abstract
For the purpose of choosing correct parameter in future experiments,numerical analysis of the transient-state of the Yb3+-doped double clad fiber laser used in the master-oscillator power amplifier(MOPA)system has been preformed. The pump power density distribution and reverse population density distribution,the effect of the fiber length and input light pulse energy on the output power have been analyzed. These results are benefit for the design of MOPA's parameters such as fiber length,pump power and master-oscillator's power in experiment.
