“…3(a) shows the optical spectra centered at 1873.5 nm with a SNR value of ∼55 dB. The spectra have the same profile for the pump power in the range between 0.88 W and 4.5 W. Because that the DSR light pulse have a low linear chirp across the pulse, except at the edges, where the chirp changes exponentially [32]. As it can be expected from DSR laser operation, as the pump power is increased, the duration of the squared pulses increases [see Fig.…”

We experimentally demonstrate dissipative soliton resonance effect in a 173-m long passively mode-locked figure-eight thulium doped fiber laser with a net anomalous dispersion. The duration of the wave-breaking-free pulse broadens with the increase of a pump power. At maximum pump power of 4.5 W, square pulses were generated with duration of 85.18 ns, average output power of 245 mW, pulse energy of 206 nJ, and repetition rate of 1.19 MHz.

“…Temporally, with peak power fixed, the resonant pulse evolves from Gaussian to flat-top profile. The central plain wave and the fronts were found to feature different chirps: a moderately low linear chirp throughout the extended central plain wave and large linear chirps across both fronts [58,63]. Spectrally, a DSR pulse shows a spectrum with broadband rectangular pedestal which corresponds to the fronts.…”

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.

“…Next, we measured the instantaneous frequency (IF) profile of the output light pulses by using a simple technique previously developed by us [20] and successfully applied since [21], [22]. The technique only requires the measurement of the temporal intensity waveforms at the input and output of the dispersive line together with the knowledge of the chromatic dispersion of the optical fiber; then the IF profile is obtained just by using a single equation in a non-iterative singlestep numerical calculation which is shown in Figure 3(b).…”

All Polarization-Maintaining Passively Mode-Locked Yb-Doped Fiber Laser: Pulse Compression Using an Anomalous Polarization-Maintaining Photonic Crystal Fiber

We report the generation of short pulses at 1 μm using an all-polarizationmaintaining (PM) fiber configuration. The pulses are provided by an all normal-dispersion Fabry-Perot Yb-doped cavity and are compressed with an anomalous polarizationmaintaining photonic crystal fiber (PM PCF). Opposed to standard configurations; here the filtering action is solely performed by the finite bandwidth of the gain medium. The laser generates 8 ps width sech 2 profile pulses at 1046.8 nm with a −10 dB bandwidth of 5.9 nm. After compression using the PM PCF, pulses with an FWHM of 3 ps were obtained, limited by the actual value of the available anomalous dispersion. We also report the changes in the output light pulses when both the net-normal dispersion of the cavity and the medium gain length were varied. We found that the lack of a specific filter within the cavity does not deteriorate the performance as compared with previous works.
