“…Different from the MLFL, the SBS effects can be formed in the Qswitched random lasers 125 and the self-pulsing fiber lasers. 127 The influence of SBS can introduce a trigger effect for the RW generation. It can be believed that the observations of RWs in various fiber lasers will attract more attention in the future.…”

“…Boukhaoui et al numerically studied the influence of SBS on the occurrence of RWs in self-pulsing fiber lasers. 127 They showed that the RW generation in the SBS process is highly related to high-order Stokes generation while acoustic noise effect is negligible for the occurrence of extreme events. Recently, dissipative RWs generated in a linear cavity normal dispersion ytterbium-doped fiber laser have been reported.…”

Rogue waves (RWs) are rare, extreme amplitude, localized wave packets, which have received much interest recently in different areas of physics. Fiber lasers with their abundant nonlinear dynamics provide an ideal platform to observe optical RW formation. We review recent research progress on rogue waves in fiber lasers. Basic concepts of RWs and the mechanisms of RW generation in fiber lasers are discussed, along with representative experimental and theoretical results. The measurement methods for RW identification in fiber lasers are presented and analyzed. Finally, prospects for future RW research in fiber lasers are summarized.

“…One of the most important features of SBS lasing relates to contribution of multi-order Stokes components in SBS pulse evolution, the effect recently theoretically studied in ref. [30], [31] and experimentally observed in a multi-pass YDF based amplifier, seeded by a DFB laser; see ref. [27].…”

We report the results of an experimental study of an ytterbium-doped fiber laser with low Q-factor cavity. We demonstrate that the laser operates in two randomly alternating sub-regimes, quasi-CW (QCW) and self-Q-switching (SQS), the latter ignited by stimulated Brillouin scattering (SBS). We show that probability of each sub-regime depends on pump power: QCW dominates slightly above the laser threshold while SQS pulsing prevails at higher pump powers. We also discuss the featuring details of QCW sub-regime and its role in instabilities (jittering) of SBS-boosted SQS pulsing as well as the statistical properties of the latter.

“…Stimulated Brillouin scatttering (SBS) could once appear as a very well understood nonlinear phenomenon in optical fibers and waveguides, with a robust coherent three-wave model [1,2] fully accounting for its extremely rich dynamics in 1D-media such as single-mode silica optical fibers (SMF). Indeed, besides the common 'SBS mirror' [3,4], both self-stabilized ultracoherent regimes [5][6][7][8], bifurcations [9] and bistability [10], soliton regimes [6,11], SBS chaos [12,13] and even SBS rogue waves [14,15] in SMFs are well described by this 3-wave model.…”

While usually negligible in standard optical fibers, the group velocity dispersion of acoustic waves may in some cases play a significant role in the dynamics of stimulated Brillouin scattering (SBS) in propagation medias with more complex structures, such as microstructured fibers. The usual 3-wave coherent model of SBS can be adapted to take a perturbative acoustic dispersion into account, but the slowly varying envelopes approximation does not hold for stronger values of the acoustic dispersion, which call for a more sophisticated inertial model of SBS. A new regime of SBS mirror with a spatially inverted acoustic profile is predicted in this limit. In presence of strong acoustic dispersion, this regime exhibits a higher conversion efficiency than the usual mirror in the dispersionless case, as well as nonlinear self-stabilization of the phase of the acoustic wave when the pump is strongly depleted. Formal calculations allow the identification of regions of strong dynamic dispersion.
