摘　　要：建立了侧面抽运掺Yb3+双包层光纤激光器的数值模型,推导出激光分布的近似解析式,并进行了数值模拟,得到了光纤内抽运光和激光功率的分布特性,以及激光输出功率随抽运光注入位置,光纤长度以及端镜反射率的变化关系.结果表明,抽运光注入位置对激光分布和激光输出功率有较大的影响.The numerical model of side-pumped Yb^3＋-doped double-clad fiber laser was presented. An approximate analytic function of distributed laser along the whole fiber was obtained. The distribution of pump power and laser power, and the dependence of output power on pump position, fiber length and mirror reflectivity were analyzed. The results show that pump position greatly affects the distribution of laser power and output power.
