“…Despite operation in the anomalous dispersion regime provides the easiest access to multiple pulse formation required in the soliton rain dynamics, similar dynamics were observed with fiber ring lasers operated in the normal dispersion regime [33,46]. In addition, soliton rain has been reported in a figure-of-eight fiber laser [34].…”

a b s t r a c tWe review our recent experimental and theoretical results addressing the dynamics of large numbers of solitons interacting in presence of a background in passively mode-locked erbium-doped fiber lasers. We first characterize experimentally the soliton rain complex dynamics, and then we focus on ordered soliton patterns. We report that, for suitable experimental parameters, a continuous wave can impose harmonic mode locking. Two levels of modeling for a mode-locked laser subjected to the external injection of a continuous wave are developed to support the latter observation. The first one is based on a scalar master equation, while the second one takes into account the mode-locking mechanism more accurately through a vectorial approach.

“…Secondly, the long intra-cavity EDF and SMF could introduce large dispersion and nonlinearity, which can induce much richer phenomenon and generate pulses with various features. Rectangular-shape pulses, soliton rains and dissipative soliton resonant have been reported in fiber laser with a long cavity length 8 36 55 . Thirdly, fiber laser with long cavity length is generally sensitive to the environmental fluctuation, such as the temperatures, strains and vibrations.…”

Molybdenum disulfide (MoS2), whose monolayer possesses a direct band gap, displays promising applications in optoelectronics, photonics, and lasers. Recent researches have demonstrated that MoS2 has not only a significant broadband saturable absorption performance, but also a higher optical nonlinear response than graphene. However, MoS2 shows much lower optical damage threshold owing to the poorer thermal conductivity and mechanical property. Here, we exploit a MoS2-clad microfibre (MCM) as the saturable absorber (SA) for the generation of ultrashort pulses under different dispersion conditions. The improved evanescent field interaction scheme can overcome the laser-induced thermal damage, as well as take full advantage of the strong nonlinear effect of MoS2. With the MCM SA, conventional, dispersion-managed, and dissipative solitons are generated around 1600 nm in Er-doped fibre lasers with anomalous, near-zero, and normal cavity dispersions, respectively. Our work paves the way for applications of 2D layered materials in photonics, especially in laser sources.

“…Even with the pump power and the cavity firmly fixed, the intensities and the positions of the minor sub-pulses frequently fluctuated and randomly drifted between the adjacent major pulses. This multi-pulse phenomenon resembles the so-called soliton rain regime, which was firstly proposed and investigated in NPR-based Er-doped fibre lasers 27 28 , and also observed in Graphene-oxide mode-locked Yb-doped fibre laser 29 and NOLM-based Tm-doped fibre lasers 30 . Soliton rain consists of three key parts: the major condensed soliton phase (which corresponds to the major pulse in Fig.…”

Pulsed fibre lasers operating in the eye-safe 2 μm spectral region have numerous potential applications in areas such as remote sensing, medicine, mid-infrared frequency conversion, and free-space communication. Here, for the first time, we demonstrate versatile 2 μm ps-ns pulses generation from Tm-based fibre lasers based on frequency shifted feedback and provide a comprehensive report of their special behaviors. The lasers are featured with elegant construction and the unparalleled capacity of generating versatile pulses. The self-starting mode-locking is initiated by an intra-cavity acousto-optical frequency shifter. Diversified mode-locked pulse dynamics were observed by altering the pump power, intra-cavity polarization state and cavity structure, including as short as 8 ps single pulse sequence, pulse bundle state and up to 12 nJ, 3 ns nanosecond rectangular pulse. A reflective nonlinear optical loop mirror was introduced to successfully shorten the pulses from 24 ps to 8 ps. Beside the mode-locking operation, flexible Q-switching and Q-switched mode-locking operation can also be readily achieved in the same cavity. Up to 78 μJ high energy nanosecond pulse can be generated in this regime. Several intriguing pulse dynamics are characterized and discussed.
