“…The duality of operation regime refers to the two states of operation that can be distinguished between each other by, among others, the shape of the optical output spectrum. Typically, it is said that an oscillator with dispersion compensation in a cavity has a smoother spectral shape than a system with ANDi cavity [24], [25]. Here, we observed not only a previously-known state with smoother spectral slopes, but also a subregime of the dispersion-managed dissipative solitons with features typical for ANDi systems; namely, the spectrum with specific sharp slopes.…”

“…6 Recently, three dispersion-managed 1 µm oscillators based on a nonlinear amplifying loop mirror have been demonstrated. [7][8][9] Lately, we have presented a setup mode-locked with a nonlinear optical loop mirror (NOLM) instead. 4 Here, we demonstrate a dispersion-managed Yb-doped oscillator mode-locked with NOLM as well.…”

“…On the other hand, implementing CFBG in the cavity forces the resonator to have a linear part, as the CFBG is a reflective element. Nonetheless, most setups incorporating a loop mirror and a CFBG are still characterized by a single pass through the gain medium [22]- [25].…”

“…Our previous work [24] also covered this topic in a figure-of-8 NOLMbased laser. Shi et al [25] have recently demonstrated figure-9 all-PM oscillator mode-locked by NALM and characterized it for different values of NCD. Many efforts were also put towards investigating the specifics of the oscillators at nearzero NCD.…”

Chirped fiber Bragg gratings opened up a way towards investigating dispersion-managed dissipative soliton regime in all-fiber cavities at the wavelength of 1 µm. It has been shown that dispersion management can decrease the chirped pulse duration compared to all-normal-dispersion oscillators. Recent works also prove that operation near-zero net cavity dispersion can reduce the relative intensity noise. Building such systems using only polarization-maintaining optical fibers is of great interest because of their robustness in extreme environmental conditions resulting in various applications outside research laboratories. This work presents an ultrafast Ybdoped fiber laser oscillator made entirely of polarization-maintaining optical fibers and fiberized components. Unlike in typical ring cavities, the ultrashort pulse passes through the rare-earth-doped fiber twice per cavity roundtrip. The system operates in a Raman-free dispersion-managed dissipative soliton regime at the central wavelength of 1031 nm. The negative dispersion is introduced to the cavity via a chirped fiber Bragg grating. At net cavity dispersion of –0.037 ps2, the setup delivers stable 3 nJ pulses at a repetition rate of 23.781 MHz. The oscillator, passively mode-locked with a nonlinear optical loop mirror, generates positively chirped 8.2 ps pulses, which can be compressed down to 125 fs with a temporal Strehl ratio of 0.77.

“…As compared with previous approaches by using the figure-of-9 configuration, a 750 mW CW pump beam, delivered by a single-mode LD, was coupled into the fiber loop of the oscillator. In contrast, lower pump power (95–250 mW) was usually applied by earlier experiments on the figure-of-9 configuration [ 9 , 11 , 28 , 29 ] since pulse splitting could occur with strong intensity inside the cavity. In our case, pulse splitting was restrained by the dispersion management.…”

We reported on the generation of 99.8 fs, 25 kW peak-power, dispersion-managed pulses directly from a passively mode-locked Yb-fiber laser oscillator with a figure-of-9 configuration. The introduction of strongly injected pump power and optical components with a high damage threshold enables high-power operation, while the polarization-maintaining (PM) fiber supports environmentally stable self-started mode-locking. Mode-locking in the soliton-like and negative-dispersion regime is characterized by the dispersion management via tuning the separation distances between a pair of gratings inside the cavity. The oscillator generates stable pulses with up to 40.10 mW average power at a 16.03 MHz repetition rate, corresponding to a pulse energy of 2.5 nJ. To the best of our knowledge, it is the highest peak-power directly obtained by a laser oscillator with a figure-of-9 configuration.
