In this paper, we demonstrate excellent ultrafast optical performance of ternary transition metal dichalcogenide ReS1.02Se0.98 saturable absorber with high power tolerance and large modulation depth in thulium-doped fiber laser. Q-switching with tunable repetition frequency and pulse duration, and mode-locking with high pulse energy were generated in our experiment. The average output power/pulse energy/pulse duration of the mode-locked pulse train were 313 mW/13.6 nJ/1.43 ps, respectively.

“…It is universally known that the generation of all-normal dissipative solitons (DS) with bell-shape spectra and large chirp is the result of the balance of gain, loss, spectral filtering, nonlinear effects and dispersion in the laser cavity. In 2012, Li et al demonstrated a self-started modelocked YDF laser with GO at different cavity length (Figure 8a-c (Figure 8g-i) [139]. Here, many typical low dimension materials such as graphene, TMD, TIs and so on, were applied for the ultrashort pulse generation in the 1 μm region and have been presented in Table 1.…”

Abstract Due to the unique properties of two-dimensional (2D) materials, much attention has been paid to the exploration and application of 2D materials. In this review, we focus on the application of 2D materials in mode-locked fiber lasers. We summarize the synthesis methods for 2D materials, fiber integration with 2D materials and 2D materials based saturable absorbers. We discuss the performance of the diverse mode-locked fiber lasers in the typical operating wavelength such as 1, 1.5, 2 and 3 μm. Finally, a summary and outlook of the further applications of the new materials in mode-locked fiber lasers are presented.

“…In all-normal dispersion (ANDi) ytterbium doped fiber (YDF) laser oscillators NLPs have been generated using nonlinear polarization rotation (NPR) based SA in a ring cavity [19]. Customized material based SAs such as WS 2 [20], ReS 2(1−x) Se 2x nanoflakes [21] etc have also been shown to generate NLPs in YDF oscillators. In general, in an ANDi oscillator a bandpass filter (BPF) is implemented for pulse stabilization [22,23].…”

We report generation of stable train of noise-like pulses (NLPs) from all-normal dispersion ytterbium doped all-fiber unidirectional ring cavity consisting of semiconductor saturable absorber (SeSA) without any bandpass filter (BPF). NLPs are characterized by their autocorrelation traces which exhibit ~500 fs spike riding on a broad pedestal of ~200 ps. NLP operation is also supported by its relatively broad optical spectrum along with reasonably stable longer pulse profile on oscilloscope. Numerical simulations have also been performed in detail to study the effects of cavity parameters like the cavity length, BPF bandwidth and depth of modulation (q0) of SeSA on the evolved pulses from the cavity. The simulation results suggest that stable single clean pulse (SSCP) is generated for a certain range of cavity parameters and in the absence of BPF no SSCP is possible from the cavity if the value of q0 is below a certain value. Under this condition either NLP or no pulse is generated in the simulation. Numerically simulated NLP in a ring cavity matches qualitatively with the experimentally obtained results for NLP. The study carried out on NLP will enrich database of pulse dynamics in modelocked oscillators and has potential application in optical coherence tomography and supercontinuum generation.
