摘要 应用FEMLAB软件模拟掺镱双包层光纤放大器的脉冲放大特性.计算了在915 nm前向抽运下,光纤放大器中的上能级粒子数,抽运光和放大自发辐射在光纤中的稳态分布,以及高斯脉冲和方波脉冲的输出、能量及增益特性.与文献上的结果进行比较证明了该程序的有效性. A finite-element-simulation for pulse amplification in ytterbium-doped double-clad fiber amplifier is presented by means of （finite element modeling laboratory ）FEMLAB package. The upper-level population distributions, the pump power, and the amplified spontaneous emission while under forward pumping with 915 nm are investigated. The transient output power, stored energy and gain of both Gaussian and square pulse are simulated. The obtained results are agreement well with the results reported in the experimental and other numerical studies.
