Summary: We experimentally and theoretically demonstrate soliton rains with isolated solitons and soliton bunches in a passively mode-locked fiber laser, using a mode-locker based on a nonlinear multimodal interference technique. The isolated solitons are captured at specific time intervals, corresponding to acoustic modes in different branches. The theory of nonlinear fiber optics is used to explain the mechanism of capturing isolated solitons. Our study introduces a new approach to control multi-soliton behaviors and provides insights into complex nonlinear dynamics.

Summary: This article investigates the optical soliton resonances and soliton molecules in the Lakshmanan-Porsezian-Daniel system governed by a four-order nonlinear Schrodinger equation. Using the Darboux transformation method, the system's analytical multi-soliton solutions are obtained. New soliton resonances and soliton molecules are discovered for the system by manipulating the spectrum and phase parameters. The study reveals significant properties of the soliton resonances and soliton molecules in the system.

Summary: In this study, we theoretically investigate the dynamics of quartic solitons in fiber resonators with quartic dispersion and Kerr nonlinearity. The energy-duration scaling relationship is demonstrated in the negative quartic dispersion regime. In the positive quartic dispersion regime, dissipation-induced quartic soliton formation and remarkable pulse energy increase are achieved. Additionally, pattern formation dynamics in the quartic dispersion driving fiber resonators are explored.

Summary: We demonstrate the generation of pulsating vector dissipative-soliton-resonance (DSR) pulses in an ytterbium-doped fiber laser for the first time. By decreasing the pump power, the stationary DSR pulse can evolve into a pulsating one, with periodic variations in its width and energy. Unlike conventional pulsating behavior, the peak power of the pulsating DSR pulse remains unchanged due to the strong peak-power-clamping effect.

Summary: Experimental observation of mode-locked dissipative-soliton-resonance (DSR) pulses, including single-mode DSR pulses and multimode DSR pulses, in a Yb-doped fiber laser is reported. DSR pulses in single-mode state and multi-mode state can exist at the same time and can be output stably. The multi-mode DSR pulses exhibit same linearly broadening characteristics and bell-shaped spectral shape as single-mode DSR pulses. The results would be beneficial for expanding the knowledge of nonlinear dynamics to multimode fiber lasers and provide new insights for DSR pulse output with a fully multimode structure to get larger pulse energy.

Summary: This study explores the nonlinear optical characteristics and applications of chromium oxide (Cr2O3) in ultrafast optics. A microfiber decorated with a Cr2O3 film is prepared and its nonlinear optical characteristics are examined. The results show that this device has a modulation depth of 12.52% and a saturation intensity of 0.0176 MW/cm2. Moreover, the Cr2O3-microfiber is successfully applied as a saturable absorber in an Er-doped fiber laser, generating stable Q-switching and mode-locking laser pulses.

Summary: The self-assembly of optical solitons in nonlinear dissipative systems has revealed the internal dynamics and analogies with matter molecules. Through experimental investigation, we discovered isomeric dynamics in soliton molecules, with different configurations and evolving trajectories determined by soliton interactions. These findings shed new light on ultrafast applications and the artificial manipulation of soliton molecules.

Summary: In this study, a composite material of Ag/MXene was synthesized by combining two-dimensional MXene and metal silver nanoparticles, enhancing the nonlinear absorption property and achieving broadband saturable absorption abilities. The composite material was used as a saturable absorber to modulate pulses in lasers, resulting in the realization of Q-switched pulses in ytterbium-, erbium-, and thulium:holmium-doped fiber lasers for the first time. The performance of the output pulses including wavelength, power, and stability were also discussed in detail. This work provides possibilities for the development of broadband lasers based on nanomaterials in the mid-infrared band.

Summary: The study focuses on the application of NbxRe(1-x)S2 nanosheets in ultrafast photonics. By incorporating the NbxRe(1-x)S2-microfiber saturable absorber into a net positive dispersion Er-doped fiber laser cavity, stable dissipative soliton pulses were generated. The NbxRe(1-x)S2-based mode-locked fiber laser demonstrated superior comprehensive performance compared to previous works based on 2D materials-based saturable absorbers.

Summary: In this study, stable bound pulses (BPs) were numerically obtained in an all-normal-dispersion fiber laser (ANDFL) using white noise as the initial field. It was found that there is a rhythmic behavior of the number of dissipative solitons (DSs) with the pump power, and higher pump power can trigger more frequent soliton explosions.
