摘要: 引入增益竞争是抑制单频光纤放大器中受激布里渊散射（SBS）的有效方式．在单频光纤放大器的基础上，推导了描述增益竞争双波长放大单频掺镱双包层光纤放大器的稳态速率方程组，建立了增益竞争双波长放大单频光纤放大器的理论模型；利用建立的理论模型模拟分析了信号光波长间隔、信号光种子功率比、抽运方式和增益光纤长度等因素对放大器的单频激光输出效率以及SBS抑制效果的影响．Abstract: Introducing the gain competition is an effective way to suppress stimulated Brillouin scattering （SBS） in single frequency fiber amplifier. Steady rate equation describing two-tone single frequency Yb-doped double cladding fiber amplifier with gain competition is deduced based on single frequency amplifier. A theoretical model of this kind of amplifier is set up. With this model, simulation is performed to analyze the influences of wavelength difference between signals, signal power ratio, pump configuration and length of gain fiber on output efficiency of single frequency laser, and the effect of SBS suppression.
