“…The DFT output gradually shifts into the far-field regime, displaying relevant optical spectral information at the end of this substage. This first phase of spectral broadening evolution is similar to that observed in conventional mode locking [27,30,37]. However, the second spectral broadening phase is specific and sets up the chaotic-pulse regime.…”

“…Compared with the buildup of mode-locked pulses [27,30,37], we do not observe frequency beating dynamics, due in our case to the incoherence of the pulse during the final buildup stage. In addition, we note that the vanishing of residual nanosecond pulses takes ∼50 RT, significantly longer than in the mode-locking transition.…”

The self-formation of incoherent laser pulses appears paradoxical, involving both a strong instability and a temporal localization process. Incoherent pulse regimes are nevertheless recurrent within ultrafast fiber laser dynamics. In this paper, we bring decisive experimental data, by recording in real time the buildup dynamics of incoherent pulses under different cavity dispersion regimes. Our measurements highlight different dominant mechanisms at play. Whereas soliton pulse shaping contributes to creating a chaotic bunch of pulses in the anomalous dispersion regime, incoherent pulses in the normal dispersion regime follow strongly turbulent dissipative dynamics. Numerical simulations reproduce qualitatively well the final buildup stage of observed dynamics. By displaying common dynamical features as well as disparities, these results support the development of a general concept of incoherent dissipative solitons.

“…In addition, ZnS as a transition metal sulfide and compound semiconductormaterial, has cubic sphalerite and hexagonal wurtzite crystal structures with band gaps of 3.67–3.75 eV and 3.91–3.94 eV, respectively . The properties of these particles in the photoelectric field depend largely on their size, surface morphology, and crystal structure type.…”

Zinc sulfide (ZnS), which belongs to transition metal monochalcogenides, is a semiconductor material with wide direct band gap. It can potentially show some special applications (such as luminescence, phosphor, sensors, infrared window materials, photocatalysis) by changing the morphology, size, and crystal structure of semiconductor materials. However, ZnS nanospheres have not been studied as optical modulators until now. Herein, ZnS nanospheres are synthesized by the hydrothermal method and are used to realize optical modulators in an Er‐doped fiber laser. The evanescent field effect is utilized to incorporate the ZnS nanospheres on a tapered fiber. Furthermore, with the increase in pump power, the modulation interval gradually decreases to a minimum of 34.36 ns corresponding to the modulation frequency of 29.1 MHz, which is the highest modulation frequency to our knowledge in a ring cavity all‐fiber laser. These results demonstrate ZnS nanospheres together with the interaction of dispersion and nonlinearity in optical fibers can modulate the proposed lasers. This not only provides a new method for controlling the power and frequency of all optical modulators, but also marks an important step for ZnS materials in optics research and device applications.

Pulsating behavior is a universal phenomenon in versatile fields. In nonlinear dissipative systems, the solitons could also pulsate under proper conditions and show many interesting dynamics. However, the pulsation dynamics is generally concerned with single soliton case. Herein, by utilizing real-time spectroscopy technique, namely, dispersive Fourier-transform (DFT), we reveal the versatile categories of pulsating solitons in a fiber laser. In particular, the weak to strong explosive behaviors of pulsating soliton, as well as the rogue wave generation during explosions were observed. Moreover, the concept of soliton pulsation was extended to the multi-soliton case. It is found that the simultaneous pulsation of energy, separation and relative phase difference could be observed for solitons inside the molecule, while the pulsations of each individual in multi-soliton bunch could be regular or irregular. These findings would further enrich the ultrafast dynamics of dissipative solitons in nonlinear optical systems.
