摘　　要：针对以往双包层Er Yb共掺光纤放大器理论模型存在的问题,在考虑了纤芯横截面内不同能级的粒子数分布与信号光强大小关系的基础之上,重新建立了双包层Er Yb共掺光纤放大器的理论模型。并利用该模型分析了双包层Er Yb共掺光纤放大器Er3+、Yb3+上能级的粒子数分布,以说明该理论模型的合理性。Aimed at the existed questions of last theory model of double cladding erbium-ytterbium co-doped fiber amplifier, a new one is proposed based on the consideration that the population profile of the different energy level is dependent of the signal optical intensity in the fiber core cross section. With the theory model, we numerically analyzed the uppre state population distribution of the erbium and ytterbium, the result shows its rationality.
