| 摘 要： | 基于被动锁模掺镱和掺铒光纤激光器系统输出的自相似光脉冲的啁啾提取方法，利用短时傅里叶变换和Wigner-Ville分布2种时频分析方法对于被动锁模光纤激光器系统产生的自相似脉冲进行啁啾提取，并通过数值仿真进行验证. 最后，对2种方法的优劣进行统计学特性分析，所取得的结果对于判断产生的脉冲是否是自相似脉冲提供了理论与实验依据. |

| Abstract: | The chirp extraction of self-similar pulses was studied based on passively mode-locked Yb-doped fiber laser system and passively mode-locked Er-doped fiber laser system. The authors use the time-frequency analysis methods of Short-time Fourier Transform and Wigner-Ville Distribution to extract the chirp in mode-locked fiber laser system. The result was proved through simulation experiments analysis The advantages and disadvantages of the two time-frequency analysis methods by statistical characteristics were given. The results provide the theoretical and experimental foundation for judging pulses are self-similar pulses generated by the mode-locked fiber laser system. |
| Keywords: | self-similar pulse passively mode-locked Yb-doped fiber laser system passively mode-locked Er-doped fiber laser system chirp extraction |
