“…Since then, a variety of nonlinear optical systems have been used for generating RWs. Apart from the SC process, [44][45][46][47][48][49][50][51] there are other nonlinear optical schemes, such as mode-locked pulse fiber laser [52][53][54][55] and Raman amplifier systems, 56,57 which also provided the excellent platforms for investigating the generation of RWs. However, most of these research works in versatile nonlinear optical systems are concerned with the observation of optical RWs, and there is also a strong motive to deeply investigate physical mechanisms of optical RW formation.…”

“…80 Since then, the study of dissipative RWs in fiber lasers has been rapidly developing. [53][54][55]79,[81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97] RWs in fiber lasers can be categorized by pulse duration as three types, 94 namely slow RWs, fast RWs, and ultrafast RWs. These RWs are generated by different mechanisms.…”

“…Recently, dissipative RWs generated in a linear cavity normal dispersion ytterbium-doped fiber laser have been reported. 55 The as-mentioned laser is mode locked by SESAM, and a chirped fiber Bragg grating was introduced into the cavity for dispersion compensating. It is claimed that the generation of RWs may be attributed to the filtering effect of the chirped fiber Bragg grating, which induces multipulsing instability to the cavity.…”

“…124 The consecutive single-shot spectra of RWs were presented by the time-stretching measurement. Chowdhury et al 55 presented experimental investigation of RWs in the linear cavity Yb-doped fiber laser. They employed the dispersive Fourier transform method to observe the existence of RWs and to analyze the corresponding spectral evolution.…”

“…Recently, RW generation has been reported in a linearcavity Yb-doped fiber laser mode-locked by semiconductor SAM. 55 It is noted that the authors mentioned that the SESAM plays an important role on the formation of RWs. However, there have been no systematic studies on the dynamic of RWs in a specific SA-MLFL, which would be a direction for the study in the future.…”

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.

Extreme wave events or rogue waves (RWs) are both statistically rare and of exceptionally large amplitude. They are observed in many complex systems ranging from oceanic and optical environments to financial models and Bose–Einstein condensates. As they appear from nowhere and disappear without a trace, their emergence is unpredictable and non‐repetitive, which makes them particularly challenging to control. Here, the use of genetic algorithms (GAs), which are exclusively designed for searching and optimizing stationary or repetitive processes in nonlinear optical systems, is extended to the active control of extreme events in a fiber laser cavity. Feeding real‐time spectral measurements into a GA controlling the electronics to optimize the cavity parameters, the wave events are able to be triggered in the cavity that have the typical statistics of RWs in the frequency domain. The intensity of the induced RWs can also be tailored. This accurate control enables the generation of optical RWs with a spectral peak intensity 32.8 times higher than the significant intensity threshold. A rationale is proposed and confirmed by numerical simulations of the laser model for the related frequency up‐ and downshifting of the optical spectrum that are experimentally observed.
