摘　　要：对基于SOA的主动锁模环行光纤激光器模型进行了研究,考虑了半导体光放大器的材料增益谱、载流子的空间分布、带宽放大自发辐射等因素,通过理论分析和数值模拟,得出结论:调节激光器的注入脉冲,可以输出重复频率为20 GHz,脉宽(FWHM)约为7.5ps的稳定锁模光脉冲序列,其波长可调谐范围超过40 nm。An actively mode-locked fiber ring laser with SOAs Is presented. The materal gain profile, spatial distribution of carriers and the broad-band spontaneous noise emission are considered in the model. The result of theoretical study and numerical simulations reveals that 7.5 ps stable mode-locked pulse trains at repetition rate of 20 GHz can be obtained, and the pulse trains are constant over a 40 nm tuning range.
