“…Apart from the most common single DS operation, the multiple solitons, and even several different types of solitons will appear in the laser cavity when overdriven nonlinear effects are introduced. These DSs interact with each other through various mechanisms and finally can form different multisoliton complexes, such as soliton bunch, soliton rain, soliton molecules, harmonic mode locking, as well as the formation of various coexistence states [11][12][13][14][15][16][17]. In previous studies, the characterization of multi-soliton complexes is mainly implemented by conventional detection instruments such as optical spectrum analyzer and autocorrelator.…”

Recent progress in real-time measurement technology makes it possible to spectrally characterize multi-soliton complexes. Here, we report on real-time observation to the multi-pulse structures in a net-normal dispersion mode-locked fiber laser. With careful adjustment of cavity parameters, several kinds of multi-soliton complexes, such as the coexistence of soliton singlet and soliton molecule, as well as the coexistence of different types of soliton molecules, are realized in the experiment. Real-time spectral information of each pulse under multi-soliton states can be well resolved with the dispersive Fourier transformation technique, which is markedly different from the results measured by conventional measurement instruments. Note that this is the first reported the simultaneous generation of different types of soliton molecules in a fiber laser to our best knowledge. The findings help to understand the complicated dynamics of the coexisting pattern between different kinds of dissipative solitons.
