摘　　要：将三波长反向泵浦的光纤喇曼放大器的增益优化问题转化为有约束条件的非线性规划问题,并用二次规划法求解。在优化结果的指导下,建立了实验系统,并利用放大的自发喇曼辐射谱微调泵浦功率实现了70nm带宽上平均增益为10dB、增益波动小于1dB的喇曼放大。The problem about optimizing gain flatten of backward-pumped fiber Raman amplifier using three-wavelength pumping is transformed into the question about restricted nonlinear programming, and resolved by successive quadratic programming method. Under the direction of optimization results, experimental system is established. Utilizing amplified spontaneous emission spectrum to adjust pump powers accurately, Raman gain ripple less than 1dB in 70nm gain spectrum is attained, and the average gain is 10dB.
