摘　　要：采用数值模拟的方法,对高功率铒镱共掺光纤放大器(EYDFA)中由于泵浦波长漂移导致的输出功率波动问题进行了研究。研究结果表明,通过在高功率EYDFA的泵浦端同时输入一个1.0μm波段合适波长的信号,不仅可以有效地抑制高功率泵浦下Yb波段的寄生振荡和提高输出功率,而且还可以大大降低因泵浦波长漂移导致的输出功率不稳定。该方法对于高功率稳定性EYDFA的研制具有一定的指导意义。The impact of pump-wavelength drift on the output power of high power cladding-pumped Er/Yb codoped fiber amplifiers （EYDFAs）is investigated numerically. The result shows that by co-seeding a high power EYDFA with an appropriate auxiliary signal in the 1.0 μm band can not only effectively suppress the spurious las- ing and dramatically improve the available output power, but also efficaciously reduce the output power fluctuation induced by the pump-wavelength drift. This technique is helpful to scaling the power and improving the power stability of high power EYDFAs, especially for those being pumped around 975 nm.
