摘要：
The system and method for reducing Yb to Er bottlenecking in a single frequency Er:Yb-doped fiber laser amplifier. The system is pumped off peak at about 935-955 nm. The off-peak pumping reduces bottlenecking and increases the optical and slope efficiency of the system by about 10% as compared to an EYDFA system pumped on-peak.
