Abstract

As one of the most intriguing nonlinear dissipative phenomena, soliton explosions can be characterized by the collapse abruptly of quasi-stable spectrum and then the spectrum restore to the initial state within certain roundtrips [1]. Despite the first experimental observation on soliton explosions was reported in a Kerr-lens mode-locked Ti:sapphire laser as early as 2002 [2], most related investigations in the past decades have focused on theoretical analysis and numerical simulations due to the lack of real-time high-resolution measurements. Recently, the dispersive Fourier transformation (DFT) method, making the temporal waveform of a pulse mimic its corresponding spectrum, was proposed to achieve real-time spectral measurements and apply to the investigation of the real-time spectral evolution of soliton explosions in a fiber laser [3].
