“…The formation of these two kinds of VDSs is ascribed to a result of coherent coupling between two orthogonally polarized DSs. Moreover, VDSs under incoherent coupling in normal-dispersion regime have been demonstrated as well [34]. The two orthogonally polarized DSs are characterized by large central wavelength disparity and travel together at the same group velocity in the laser cavity, forming the so-called group velocity locked vector dissipative solitons (GVLVDSs).…”

Vectorial nature of dissipative solitons (DSs) with high repetition rates is studied for the first time in a normaldispersion fiber laser. Despite the fact that the formed DSs are strongly chirped and the repetition rate is greater than 100 MHz, polarization locked and polarization rotating group velocity locked vector DSs can be formed under 129.3 MHz fundamental mode-locking and 258.6 MHz harmonic mode-locking of the fiber laser, respectively. The two orthogonally polarized components of these vector DSs possess distinctly different central wavelengths and travel together at the same group velocity in the laser cavity, resulting in a gradual spectral edge and small steps on the optical spectra, which can be considered as an auxiliary indicator of the group velocity locked vector DSs.

“…When the gain bandwidth is chosen to be narrow, e.g., 10 nm, the result of characteristically steep spectral edges is similar to that in Ref. [16]. The spectrum is shaped by the gain bandwidth directly.…”

We numerically study the vector dynamics of dissipative solitons (DSs) in a 2 μm dispersion-managed fiber laser mode locked by a semiconductor saturable absorber mirror and operated in the normal dispersion regime. It is shown that the effective gain bandwidth is crucial for the DS generation. The steep spectral edges of DSs are the consequence of the interaction among the normal dispersion, fiber nonlinearity, gain and loss, and gain dispersion effect, etc. We numerically duplicate the experimental results and further explore the vector features of the generated DSs. Two DSs formed along the two orthogonal polarization directions which, incoherently coupled with each other, could propagate in the birefringent cavity with the same group velocity.

“…Renninger et al found that there exists an exact particular solution of the cubic-quintic GLE models pulses in the normal-dispersion laser [26]. A series of research on the properties of GGSs [27][28][29][30][31][32][33][34][35][36][37][38][39] and DSs are carried out [40][41][42][43][44][45][46]. It is found that, similar to the traditional soliton generated in fiber lasers with anomalous dispersion, GGSs can express various soliton features.…”

“…The state of GGSs and that of noise-like pulses can be shuttled with appropriate operation condition tuning [30]. Based on GGSs, phenomena of multiple pulsing [31], bound states [32], harmonic mode locking [33], period-doubling [34], soliton trapping [35] could be observed. The dynamics of GGS generation under various conditions are also explored [36][37][38][39].…”

Principles of pulse shaping aiming larger pulse energy in fiber lasers are reviewed. From conventional solitons generated in anomalous dispersion regime, stretched pulses in dispersion-managed fiber lasers, similaritons in normal dispersion regime, dissipative solitons in large normal dispersion regime, amplifier similaritons in fiber lasers with narrow bandwidth filtering, to dissipative-soliton-resonance (DSR) pulses in fiber lasers, scaling of pulse energy from pico-Joule level to micro-Joule is successfully achieved. DSR is a possible way to achieve endless pulse energy, which is limited by the available pump power and material damage threshold. Properties of DSR pulses are reviewed. Specifically, we experimentally and numerically demonstrate tilt-top DSR pulses in a normal dispersion mode-locked fiber laser. Two fronts of the tilt-top pulses exhibit different intensity, and the intensity disparity maintains while the pulses extend with increasing gain. The tilt-top DSR pulses have rectangle spectral pedestal and a peak. The spectral peak deviates from the center of the rectangle spectral pedestal. Further results show that the asymmetry of two fronts is closely related to the wavelength deviation of spectral peak. Numerical simulations reveal the importance of the saddle-type spectral filtering on asymmetric DSR pulse generation.
