外文摘要：We have recently demonstrated an Er:Yb fiber amplifier pumped off-peak at 940 nm which achieved 50。5% slope efficiency compared to 40。2% slope efficiency when pumped on-peak at 976 nm， the typical pumping wavelength for Er:Yb fiber。 To further understand these results we implemented a model that predicts the behavior of high power Er:Yb-co-doped fiber amplifiers with strong correlation to data。 Through this modeling effort， we were able to estimate the forward and backward energy transfer coefficients for the Er:Yb silicophosphate fiber used。 We also conducted a theoretical cutback experiment to find the optimal amplifier fiber length for each pump wavelength。
