“…In other words, one can measure the optical spectrum of optical pulses in real time. Time-stretching methods have been widely employed in the experimental investigation of optical pulses in the fiber lasers by researchers, including the dissipative solitons, 52,129,130 soliton molecules, 131-133 chaotic pulses, 134,135 intermittent pulses, 78,136 transition dynamics, and other nonlinear dynamics. [137][138][139] In 2014, the Raman RW generation in the pulse fiber lasers was provided by the research group of Runge et al 82 By employing the pulse stretching method, the statistical histograms of wave events in more detail were investigated and the spectral evolution of RWs in real time was analyzed.…”

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.

“…There is currently much interest in the real-time characterization of mode-locked dissipative soliton fiber laser dynamics. Dispersive Fourier Transform measurements of spectral variations are a particular focus, revealing soliton build up dynamics [1][2][3][4][5], soliton molecules with internal motion [6,7], and soliton explosions and pulsations [8][9][10][11][12][13][14]. Work has also reported complex intermittence where a laser randomly alternates between sequences of metastable molecules, explosions, and chaos [15].…”

“…A lumped linear intracavity loss of 2.2 dB was applied after the filter to model output coupling and insertion losses. Simulations used 2 13 points, a 500 ps time span, and adaptive spatial steps. In this regime, this model has previously reproduced linearlychirped parabolic pulses as seen in experiment [15].…”

Numerical simulations of a dissipative soliton-similariton laser are shown to reproduce a range of instabilities seen in recent experiments. The model uses a scalar nonlinear Schrödinger equation map, and regions of stability and instability are readily identified as a function of gain and saturable absorber parameters. Studying evolution over multiple round trips reveals spectral instabilities linked with soliton molecule internal motion, soliton explosions, chaos, and intermittence. For the case of soliton molecules, the relative phase variation in the spectrum is shown to be due to differences in nonlinear phase evolution between the molecule components over multiple round trips.

“…[ 13,15,16 ] More importantly, besides being used as an excellent pulse source, ultrafast fiber laser can provide a suitable testbed for exploring the nonlinear soliton dynamics. [ 17,18 ] So far, researchers have demonstrated the many kinds of interesting soliton pulses, including noise‐like pulses, [ 19 ] soliton rains, [ 20 ] soliton pulsation, [ 21 ] soliton explosion, [ 22 ] and breathing solitons, [ 23 ] which gradually become the focus of research in recent years. Actually, when the ultrafast fiber laser operates in the net anomalous dispersion region, the multiple soliton pulses easily appear at the high pump power because of the peak‐power‐limiting effect.…”

Transition metal nitride materials exhibit unique optical characteristics and have attracted much interest for various applications, including waveguiding, photovoltaics, and nonlinear optical devices. Herein, titanium nitride (TiN), as a typical representative of biocompatible transition metal nitrides, is prepared and modified with gold nanoclusters (Au NCs) for promoting the carrier mobility, and the corresponding physical characteristics are systematically characterized. The TiN‐based saturable absorber (SA) on microfiber is fabricated and its nonlinear optical absorption property is also studied experimentally. Furthermore, the TiN‐decorated SA is applied in an ultrafast fiber laser at the communication bands. The fiber laser can generate the stable ultrashort pulses with a pulse width of 1.66 ps, a fundamental repetition rate of 7.49 MHz, and a spectral bandwidth of 2.61 nm. More importantly, the chaotic multiple pulses can be obtained, which is reported for the first time in the fiber laser based on the TiN SA on microfiber as far as it is known. The chaotic multiple pulses show many interesting characteristics, including high average pulse energy, varying pulse separations, and pulse intensities. These results have proved that the TiN shows great potential in many fields, such as advanced optical‐intensity modulator, ultrafast pulse dynamics, and optical fiber communications.
