“…Real-time spectrum characterization of multi-soliton complexes in a normal dispersion passively mode-locked fiber laser recorded by the DFT technique revealed the existence of multi-soliton complexes containing nine distinct single-soliton pulsations [113]. Each soliton might evolve periodically in a different way and present the typical characteristic of soliton pulsations in a multi-solitons complex containing one pulsating three-soliton molecule and one pulsating single-soliton [127]. These findings contribute to a better understanding of the dynamics of multi-soliton passively mode-locked fiber lasers.…”

Research has shown that passively mode-locked fiber lasers produce chaotic output, which has caught the attention of physicists, chemists, and bio-scientists owing to their wide bandwidth, good random characteristics, and strong anti-interference. In passively mode-locked fiber lasers, soliton pulsations and soliton explosions with period bifurcation characteristics have been demonstrated to be effective paths to chaos as far as 20 years ago. However, due to the lack of real-time spectrum measurement techniques, the earlier research investigated their theoretical aspect. In recent years, the rise of the dispersive Fourier transform technique has activated an upsurge of their experimental research. The present work first discussed the theoretical model of passively mode-locked fiber lasers, the computational analysis method of soliton dynamics, and the related theory of dispersive Fourier transform technique. In addition, we presented and evaluated the progress of the theoretical and experimental research on soliton pulsations as well as on soliton explosions in passively mode-locked fiber lasers. Finally, we proposed the future research directions of the soliton pulsations and soliton explosions that offer great promise for scientific discoveries.

“…A variety of soliton transient dynamics was observed in passively mode-locked fiber lasers adopting the DFT technique: the build-up of dissipative soliton pulsation, [14] successive soliton explosion, [15] explosion induced rogue waves. [16] Breathing behavior of dissipative soliton pulsation, [17][18][19] multiple soliton pulsation, [20,21] dissipative soliton explosion [22] and the pulsating soliton molecule [23] are observed in the normal dispersion NPR mode-locked fiber laser by the DFT. In the anomalous dispersion region, the soliton pulsation with chaotic behavior [24] and the soliton pulsation sideband characteristics [12] are also studied.…”

We have numerically and experimentally observed the soliton pulsation with obvious breathing behavior in the anomalous fiber laser mode-locked by nonlinear polarization rotation technique. The numerical study of the soliton pulsation with breathing behavior was analyzed through the split-step Fourier method at first, and it was found that the phase difference caused by the polarization controller would affect the breathing characteristics. Then, taking advantage of the dispersive Fourier transform technique, we confirmed the breathing characteristic of soliton pulsation in the same fiber laser as the simulation model experimentally. These results complement the research on the breathing characteristic of soliton pulsation.

“…[8,9] Through time-stretch method, the pulse spectrum can be mapped into a temporal waveform to obtain the real-time spectral information. Hence, utilizing DFT, various complex ultrafast nonlinear phenomena, such as soliton explosions, [10][11][12] soliton pulsations, [13,14] and soliton buildup dynamics, [15][16][17] as well as internal motions of soliton molecule, [18][19][20] have been well investigated.…”

We present experimental observations of soliton pulsations in the net normal-dispersion fiber laser using the dispersive Fourier transform (DFT) technique. According to the pulsating characteristics, the soliton pulsations are classified as visible and invisible soliton pulsation. The visible soliton pulsation converted from single- to dual-soliton pulsation with the common characteristics of energy oscillation and bandwidth breathing. The invisible soliton pulsation underwent periodic variation in the spectral profile and peak power but remained invariable in pulse energy. The reason for invisible soliton pulsation behavior was periodic oscillation of the pulse inside the soliton molecule. These results could be helpful for deepening our understanding of the soliton pulsation phenomena.
