Abstract

The impact of pump-wavelength drift on the output power of high power cladding-pumped Er/Yb co-doped fiber amplifiers (EYDFAs) is investigated numerically. The results show that by co-seeding a high power EYDFA with an appropriate auxiliary signal in the 1.0 m band can not only effectively suppress the spurious lasing 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 scale the power and improve the power stability of high power EYDFAs, especially for those being pumped around 975 nm..
