“…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.…”

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.

“…The dynamics of GGS generation under various conditions are also explored [36][37][38][39]. It is numerically demonstrated that broad gain bandwidth up to 100 nm can still support DS generation subject to enough pump power [40].…”

Chirped pulse amplification in an all-normal-dispersion erbium-doped fiber amplifier is presented. Wavelength dependent amplification is examined. It is found that gain dispersion limits the spectral profile of the amplified pulse. If the central wavelength of the seed pulse is far away from that of the gain profile of the amplifier, the gain profile partially shapes the spectrum of the amplified pulse while maintaining the characteristic steep spectral edge at one side. If the optical spectrum of the seed pulse is most covered by the gain profile, the characteristic steep spectral edges will be both maintained. The amplified pulse becomes deformed ultimately with increasing pump power, no matter whether the seed pulse is a transform-limited pulse or a chirped pulse.

Dissipative vector soliton in a dispersion-managed fiber laser with normal dispersion

et al. 2014

View full text Add to dashboard Cite

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.
