In order to study the impact of amplified spontaneous emission(ASE)generation on the performance of high power Er/Yb co-doped fiber pulse amplifiers,based on the rate equation,the theoretical models for several amplifiers with different pump,signal and configure parameters were solved with finite difference method.The results show that because of the ASE self-saturation,there is an optimal repetition rate for the input signal in order to achieve the highest peak power and maximum pulse energy and the repetition rate is linear with the pump power and inverse to the pulse duration.The results are important for the design and experimental research of high power Er/Yb co-doped fiber pulse amplifiers.
