摘　　要： 从铒离子在玻璃基质的能级结构出发,分析掺铒光纤光源工作机理,建立光纤光源物理模型,即泵浦光和信号光沿铒纤的传播方程.将荧光光谱划分为10个波长带,模拟算法的核心为求解21维常微分方程的边值问题.采用打靶法将常微分方程的边值问题转化为初值问题,使用龙格-库塔法求解,用Visual C++编程实现.该数值模拟算法及软件实现对掺铒光纤放大器和激光器的研究提供了借鉴. Based on the energy level of erbium ions in the glass matrix, we analyzed the work mechanism of erbiumdoped fiber super-fluorescent light source. The physical model of light source was set up, which was described by propagation equations of pump light and signal light along the erbium-fiber. By dividing the fluorescence spectra into 10 wavelengths, the issue was solving the boundary value problem of 21-dimensional ordinary differential equations. We translated the boundary value problems into an initial value problem using shooting method. The equations were solved using Runge-Kutta method. We wrote a program ＇to implement the algorithms using Visual C ＋＋. The numerical simulation and software can provide directions for researching on erbium-doped fiber amplifiers and lasers.
