Abstract

In this Letter, high-power cladding-pumped Er:Yb-codoped fiber amplifiers (EYDFAs) coseeded with a Yb-band signal are numerically characterized according to the wavelength and power of the aiding signal, the length of the gain fiber, and the wavelength of the pump. The results show that properly designing these parameters not only helps to suppress the parasitic lasing and improve the pump conversion efficiency but also helps to improve the output power stability of high-power EYDFAs.
