摘　　要：为了获得稳定的超短脉冲序列,采用分步傅里叶算法数值分析了滤波器带宽、可饱和吸收体调制深度和可保和吸收体恢复时间对锁模的影响,并搭建了一个利用半导体可饱和吸收镜作为可饱和吸收体的全保偏结构的掺镱锁模光纤激光器。结果表明,该腔体可以自启动产生光谱带宽为0.104 nm、重复频率为102.32 MHz的耗散孤子脉冲序列;且出射的脉冲在放大过程中表现出缓慢的展宽速率,激光腔搭建成功。该激光器在光纤探针、频率梳和参量光学等领域具有良好的应用前景。To obtain the stable mode-locked pulse train,the effects of filter bandwidth,saturable absorber(SA)modulation depth,and SA recovery time on mode-locking were analyzed numerically by the split-step Fourier method.According to the calculation results,the laser is established.The oscillator can generate self-starting dissipative soliton pulses train with a spectrum bandwidth of 0.104 nm and a repetition rate of 102.32 MHz.Meanwhile,the pulse train shows a slow broadening rate and good shape-preserving ability in the amplification process.This study indicates that this laser will have great application prospects in fiber probes,frequency comb,parameters optic and other fields.
