%X <p>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.</p>
