Abstract :
In this contribution, we obtain self-similar propagation of high-energy, ultrashort, parabolic pulses in a passively mode-locked Yb-doped fiber laser by numerical simulation using our non-distributed model. For extracting the chirp of these wave-breaking-free self-similar solitons to research characteristics of them, we propose several methods to accomplish the extraction and then discuss the advantages and disadvantages of these time-frequency analysis methods in this particular application.
