“…The initial pulse separation could be changed from several nanoseconds to sub-nanosecond (when initial pulse separation was very small, the two-pulse bunch was resolved as a single pulse from the oscilloscope, where real pulse separation is proportional to width of the single pulse displayed by the oscilloscope). Change of the initial pulse separation via PC adjustment may be related to electrostrictive effect [69] or gain depletion and recovery [70,71], as well as interaction force incurred by dispersive waves [66]. Experimental experiences provide an essential evidence that a bound state was frequently obtained when the initial pulse separation was adjusted to be sub-nanosecond or less, although it is impossible to foresee which kind of bound states will be obtained.…”

“…Simultaneously, indirect interaction is very common via long-range media such as dispersive waves, continuous-wave emission [31] and acoustic waves [69,80]. They influence interaction forces by again changing the refractive indices of the optical fibres, so that widely spaced pulses are able to feel each other and possess distinct group velocities.…”

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.

“…Specifically, the stable interspacing for the well-developed rain is observed to be close to 2.5 ns, which can be attributed to the electrostrictive response of SMF [4,5]. This suggests that the solitons in the rain interact via FBS, which results in their observed self-organization, much like that observed in a mode-locked fiber laser [6], or more recently in the bunching of temporal cavity solitons in a passively driven cavity [7].

“…Indeed, the current schemes of either external nonsoliton ASE or intracavity continuous-wave pump controlling are relatively global. For a more localized control, the external ASE source can be replaced by a synchronized single-pulse excitation, which thus can produce a localized acoustic wave through electrostriction [38]. It is an effect that the electric field of injected single-pulse can deform the optical fiber and thus generate an acoustic wave, which results in a small timevarying change of refractive index.…”

Passively mode-locked fiber lasers have been intensively applied in various research fields. However, the passive mode-locking typically operates in free-running regime, which easily produces messy multiple pulses due to the fruitful nonlinear effects involved in optical fibers. Actively controlling those disordered pulses in a passively mode-locked laser is of great interest but rarely studied. In this work, we experimentally investigate a flexible pulse-spacing manipulation in the passively mode-locked multipulse fiber laser by both intracavity and extracavity methods. A tuning range of pulse spacing up to 1.5 ns is achieved. More importantly, continuous pulse-spacing modulation is successfully demonstrated through external optical injection. It is anticipated that the results can contribute to the understanding of laser nonlinear dynamics and pursuing the optimal performance of passively mode-locked fiber lasers for practical applications.

Acoustic effect in passively mode-locked fiber ring lasers

Abstract: We present a theory of acoustically induced pulse interaction in a ring fiber laser cavity. In most cases the acoustic interaction leads to pulse bunching, but in some cases it leads to regular pulse spacing. Our results compare well with the experimental data.
