摘　　要：分析了Raman放大器的数学模型,提出了一种新的步长预测方法,给出了这种步长的数学表示,从而得到了一种新的后向泵浦Raman放大器的分析和计算方法.仿真结果表明,该方法收敛速度快、精度高,同等精度下,较一般方法快60%,可很好地应用于Raman光纤放大器的优化和性能分析.Analyzing backwardly pumped Raman fiber amplifier is a problem of solving two-boundary ordinary differential equations in mathematics. Traditional shooting method with equal and varying steps is not efficient. Based on the mathematical model of Raman fiber amplifier, a novel step predicting method was proposed and mathematical expressions were given. The novel algorithm leads to quicker convergence and higher accuracy. It can save 60% of time in comparison with the general methods with the same accuracy.
