“…[41] Recently, passively mode-locked fiber lasers have drawn great interest and been regarded as an ideal method to directly generate such kind of laser pulses. [42][43][44][45][46][47] SWP mode-locked fiber lasers were ever-reported to be generally based on the nonlinear polarization rotation and nonlinear amplifying loop mirror mechanism. [45,48] New materials-based SAs have rarely been reported to produce SWP mode-locked fiber lasers.…”

optical computers, optical switches, pulsed laser generation, optical sensors, etc. As the fundamental information carrier of NLO, nonlinear optical materials have attracted great attention since the advent of the first laser and always been the research hotspot for material and optical scientists. In the last two decades, 2D materials, representative of the main including graphene, [1-3] topological insulators (TIs), [4-6] transition metal disulfides (TMDs) [7,8] and black phosphorus (BP), [9-11] have experienced an explosive growth because of the advantages of exotic optical, electronic, chemical, and mechanical properties that much differ from their bulk counterparts. Especially, the low dimensions and distinctive nonlinear optical properties make them strongly meet the ever-increasing demand and widely used in high efficiency, compactness, broadband optoelectronic and photonic devices, broadband all-optical modulator, optical frequency conversion, pulsed laser generation, surface plasmonic, and so on. [12-19] However, there are still some disadvantages for the current 2D materials. For example, the gapless band structure and relative low light absorption of graphene limit its extensive applications; [20,21] the band gap of TMDs (1.0-2.0 eV) indicates they cannot be available in mid-infrared wavelength range; [22,23] and easy oxidation is the biggest obstacle for practical applications of BP. [24,25] Therefore, it is still an urgent demand to explore promising novel 2D nonlinear optical materials. Recently, 2D MXenes have been extensively studied due to the unique optical and electronic properties. [26,27] MXene represents a large family of 2D transition metal carbides, carbonitrides, and nitrides, with the general formula of M n+1 X n T n (n = 1-3), where M represents a transition metal (e.g., Ti, Mo, Nb), X for either C and/or N, and T is the surface functional group (e.g.,-OH,-O, and-F). [28,29] Until now, more than 30 varieties of 2D MXenes have been synthesized and theoretically and experimentally studied, [30-34] revealing the outstanding features of metallic conductivity, large electric capacity, high mechanical strength, tunable band gap, high stability, high optical transparency, and large optical nonlinearities of MXenes. [35,36] Nb 2 C is a newly discovered 2D MXene with special band structure near the Fermi level, showing the great potential applications as electrode materials Niobium carbide (Nb 2 C), a newly developed 2D MXene material, has attracted much attention due to its outstanding electronic and optical properties. In this work, few-layer 2D Nb 2 C nanosheets are synthesized by magnetron sputtering deposition method. Z-scan measurements with pump source operating at 1.0 µm are performed to study the third-order nonlinear optical response, revealing excellent light modulation capabilities of 2D Nb 2 C. The effective nonlinear absorption coefficient (β eff ≈-10 5 cm GW-1) caused by saturable absorption effect is determined to be two orders of magnitude larger than that induced by reverse sat...

“…On the other hand, the mode-locking method [ 12 ] comprising a concurrent in-phase lock of all the longitudinal modes in the cavity is frequently employed for producing extremely-short pulses ranging from a few femtoseconds to several picoseconds. Furthermore, the mode-locked pulse repetition rate is quite higher compared to the Q-switching repetition rate [ 13 ].…”

A Review on Rhenium Disulfide: Synthesis Approaches, Optical Properties, and Applications in Pulsed Lasers

Rhenium Disulfide (ReS2) has evolved as a novel 2D transition-metal dichalcogenide (TMD) material which has promising applications in optoelectronics and photonics because of its distinctive anisotropic optical properties. Saturable absorption property of ReS2 has been utilized to fabricate saturable absorber (SA) devices to generate short pulses in lasers systems. The results were outstanding, including high-repetition-rate pulses, large modulation depth, multi-wavelength pulses, broadband operation and low saturation intensity. In this review, we emphasize on formulating SAs based on ReS2 to produce pulsed lasers in the visible, near-infrared and mid-infrared wavelength regions with pulse durations down to femtosecond using mode-locking or Q-switching technique. We outline ReS2 synthesis techniques and integration platforms concerning solid-state and fiber-type lasers. We discuss the laser performance based on SAs attributes. Lastly, we draw conclusions and discuss challenges and future directions that will help to advance the domain of ultrafast photonic technology.
