“…We use the term "rogue waves" for these pulses to outline their physical similarities with the extreme events in optical systems and hydrodynamics. Moreover, the rogue waves in gyrotrons can reach intensities at least a factor of 100  150 greater than the average radiation power, which significantly exceeds typical values for the extreme events in lasers [5][6][7].…”

“…can be suggested that, similar to lasers [5][6][7], the rogue waves can also occur in microwave oscillators representing active systems which are based on the interaction of electromagnetic waves with non-equilibrium electron beams.One of the widely studied microwave oscillators is a gyrotron in which a helical electron beam excites a waveguide mode near its cutoff frequency [10]. In this paper, we demonstrate that rogue waves can appear in gyrotrons operating in the regime of developed turbulence.…”

Within the framework of the average approach and direct 3D PIC (particle-in-cell) Many physical systems exhibit behavior associated with the emergence of the so-called rogue waves which represent dramatically high-amplitude events that occur with low probability but much more frequently than expected in ordinary (e.g., Gaussian or Rayleigh) wave statistics. can be suggested that, similar to lasers [5][6][7], the rogue waves can also occur in microwave oscillators representing active systems which are based on the interaction of electromagnetic waves with non-equilibrium electron beams.One of the widely studied microwave oscillators is a gyrotron in which a helical electron beam excites a waveguide mode near its cutoff frequency [10]. In this paper, we demonstrate that rogue waves can appear in gyrotrons operating in the regime of developed turbulence. It is well known that in electronic oscillators, including gyrotrons, an increase of the excess over the starting conditions leads to a complication of the radiation spectrum caused by the appearance of periodic self-modulation and then chaotic turbulent generation regimes [11][12][13][14][15][16][17]. Typically, realization of self-modulation regimes is a result of combination of a nonlinearity and delay effects [12].

“…In particular, optical RWs go beyond the significant wave height by a factor of 2, which have been widely investigated in different nonlinear optical systems, such as mode-locked Ti:sapphire lasers [94], Raman fibre amplifiers [95,96], parametric processes [97] and fibre lasers [98][99][100][101][102][103][104][105][106]. Figure 26 shows typical characterizations of dissipative RWs, which were obtained in a Tm-doped fibre laser mode-locked by monolayer MoS 2 [107].…”

Featured Application: High-capacity telecommunication, advanced time-resolved spectroscopy, self-organization and chaos in dissipative systems. Abstract:Benefiting from ultrafast temporal resolution, broadband spectral bandwidth, as well as high peak power, passively mode-locked fibre lasers have attracted growing interest and exhibited great potential from fundamental sciences to industrial and military applications. As a nonlinear system containing complex interactions from gain, loss, nonlinearity, dispersion, etc., ultrafast fibre lasers deliver not only conventional single soliton but also soliton bunching with different types. In analogy to molecules consisting of several atoms in chemistry, soliton molecules (in other words, bound solitons) in fibre lasers are of vital importance for in-depth understanding of the nonlinear interaction mechanism and further exploration for high-capacity fibre-optic communications. In this Review, we summarize the state-of-the-art advances on soliton molecules in ultrafast fibre lasers. A variety of soliton molecules with different numbers of soliton, phase-differences and pulse separations were experimentally observed owing to the flexibility of parameters such as mode-locking techniques and dispersion control. Numerical simulations clearly unravel how different nonlinear interactions contribute to formation of soliton molecules. Analysis of the stability and the underlying physical mechanisms of bound solitons bring important insights to this field. For a complete view of nonlinear optical phenomena in fibre lasers, other dissipative states such as vibrating soliton pairs, soliton rains, rogue waves and coexisting dissipative solitons are also discussed. With development of advanced real-time detection techniques, the internal motion of different pulsing states is anticipated to be characterized, rendering fibre lasers a versatile platform for nonlinear complex dynamics and various practical applications.

Dual‐wavelength mode‐locking lasers delivering asynchronous dual‐color solitons are excellent sources for dual‐comb spectroscopies. Up to now, diverse approaches have been developed to implement dual‐wavelength lasers. However, the buildup dynamics of dual‐color solitons have not been well revealed. Here, by means of the time‐stretch dispersive Fourier transform technique, real‐time observation of the buildup process and propagation dynamics of asynchronous dual‐color solitons in a mode‐locked fiber laser are reported. In addition to the typical phases that have been well discussed on buildup dynamics of conventional solitons, such as raised relaxation oscillation and spectral beating behavior, it is observed that optical or solitons collision plays a key role in facilitating the buildup of dual‐ or multi‐wavelength mode locking. Specifically, when the dual‐wavelength solitons carrying the same color photons encounter in the time domain, their collision induces the solitons explosion and brings about the new evolved mode‐locking pulse at another waveband. Experimental results agree well with numerical predictions and bring insights to the understanding of nonlinear dynamics in fiber lasers.
