摘要
为了研究掺镱双包层单频光纤放大器中受激布里渊散射产生的规律,从含有受激布理渊散射的速率方程和热传导方程出发,对光纤放大器中的热效应问题进行了理论分析.讨论了泵浦功率、包层半径和换热系数对受激布理渊散射的影响,所得结论为实验研究单频光纤放大器中受激布理渊散射的变化规律提供了理论依据.
In order to study Stimulated Brillouin Scattering（SBS） in Yb3＋-doped double clad single-frequency fiber amplifier,thermal effects of the fiber amplifier were analyzed theoretically,based on the rate equations and heat transfer equations.The impacts of the fiber temperature,which can broaden the SBS gain profile and suppress SBS,on the amplifier performances were discussed.The relationships between the SBS and pump power,signal power,heat transfer coefficient were simulated.The results of simulation provide theoretical guide to optimum design of high power single-frequency fiber amplifier.
