“…In particular, MoSe2 also has a high third-order nonlinear refractive index (10 -11 m 2 /W) [19], which is much higher than topological insulator [20] and carbon nanotubes [21], this property contributes to the generation of solitions. Relevant experiments have proved that the saturation absorption characteristics of MoSe2 can obtain traditional soliton [22]- [24] or dissipative soliton [25]. So far, however, there have been no experimental reports on bright-dark soliton pairs based on MoSe2-SA.…”

In this paper, molybdenum diselenide (MoSe2) was fabricated by chemical vapor deposition (CVD) with a modulation depth of about 7.3% and nonsaturable loss of about 30.6%. Bright-dark soliton pairs have been obtained in a thulium-holmium-doped fiber ring laser based on MoSe2 as a saturable absorber (SA) for the first time, to the best of our knowledge. The results not only prove that MoSe2 can be used as an excellent saturable absorber in the field of ultra-fast optics, but also provide a certain reference value for the future research on bright-dark soliton pairs based on two-dimensional materials.

“…In ultrafast lasers, the passive optical modulator is also referred to as a saturable absorber (SA) because it shows a nonlinear optical behavior at higher light intensities. These SAs can be prepared in several ways, such as thin film [10,11], coating on tapered fibers, or direct deposition over arcshaped fibers [12][13][14]. Among them, the deposit of nonlinear optical material over arc-shaped fibers allows laser mode-locking via evanescent field interaction [12,15].…”

Two-dimensional (2D) materials have recently been explored as a potential for saturable absorbers (SA) due to their remarkable optoelectronic and nonlinear optical properties. In this work, we have experimentally reported the 2D boron carbon oxynitride (BCNO) as a potential mode-locker in erbium-(EDFL) and thulium-doped fiber lasers (TDFL) for the first time. The BCNO-coated arc-shaped fiber was explored as a novel optical loss modulator and exhibited a modulation depth of 8.2 % and 5 % at 1.5 µm and 2 µm, respectively. The mode-locked laser was then achieved by using BCNO-coated arc-shaped fiber in EDFL having a pulse width, repetition rate, and center wavelength of 1.56 ps, 19.14 MHz, and 1562.2 nm, respectively. Mode-locked pulses of 1.456 ps duration were achieved by incorporating BCNO-coated arc-shaped fiber in TDFL, operated at center wavelength, repetition rate, and signal-to-noise ratio (SNR) of 1944 nm, 13 MHz, and 70.3 dB, respectively. These results prove BCNO to be a promising low-cost 2D material to be further explored for laser-related applications.

“…Real SAbased ultrafast fiber lasers have attracted much attention because of their compactness, stability, and flexibility. Until now, many different kinds of materials have been explored and used as SAs in the ultrafast fiber laser field, such as semiconductor saturable absorber mirror (SESAM), [4] carbon nanotube (CNT), [5][6][7][8] graphene, [9] topological insulators, [10,11] transition metal dichalcogenides, [12][13][14][15][16][17] black phosphorus, [18,19] long-term stable group VA materials Xene (e.g., X = antimon, [20] bismuth [21] ), flexible gold nanomaterials (e.g., gold nanorods, [22] gold nanostars, [23] gold nanobipyramids [24] ), and so on. [25][26][27][28][29][30][31] Besides, zerodimensional core-shell structures and two-dimensional layered van der Waals heterostructures are demonstrated to enhance the nonlinear optical modulation property.…”

CsPbBr3 nanocrystal is used as the saturable absorber (SA) for mode-locking Tm-doped fiber laser in a ring fiber cavity. The modulation depth, saturable intensity, and non-saturable loss of the fabricated SA are 14.1%, 2.5 MW/cm2, and 5.9%, respectively. In the mode-locking operation, the mode-locked pulse train has a repetition rate of 16.6 MHz with pulse width of 24.2 ps. The laser wavelength is centered at 1992.9 nm with 3-dB spectrum width of 2.5 nm. The maximum output power is 110 mW with slope efficiency of 7.1%. Our experiment shows that CsPbBr3 nanocrystal can be used as an efficient SA in the 2- μ m wavelength region.
