摘　　要：增益开关半导体激光器的输出光脉冲具有“红移”啁啾，本文对具有不同时域及频域特性的啁啾光脉冲采用F－P滤波和正常色散光纤补偿两种消啁啾的效果进行了理论研究．结果表明，这两种消啁啾方法在单独运用时，都只能在一定的超短光脉冲脉宽和诺宽特性条件下，获得近变换极限光脉冲，而两种消啁啾方法的结合则可以改善消啁啾效果．实验结果也证明了理论计算的结论．The pulses from gain-switched semiconductor laser suffer serious negative chirp. Theoretical study of dechirping effects by F-P filter or/and DCF compensation for chirped pulses with different temporal and spectral characteristics is presented. The results show that only for the pulses with suitable temporal and spectral characteristics,nearly transform-limited pulses can be obtained with one of the above dechirping methods alone, good dechirping effect can be obtained by combining these two methods. Experimental results agree with the theory.
