摘　　要：采用序列二次规划算法并通过优化泵浦波长和残留功率,实现了反向泵浦的宽带拉曼光纤放大器(RFA)的增益平坦度优化,大大简化了运算过程,缩短了优化时间。并根据优化结果实现了双泵浦、三泵浦和四泵浦的宽带RFA实验系统。结果显示理论计算与实验结果具有良好的一致性,表明此优化方案具有极强的实用性。Successive quadratic programming is adopted to optimize a gain flatness of backward-pumped Raman fiber amplifier. To simplify the operation process and reduce the computation time,pump wavelengths and residual powers can be optimized. On the basis of the calculated results, broadband FRA system with two pumps, three pumps and four pumps are realized. The theoretical calculation and experimental results are accordant, showing this optimal scheme has strong practicability.
