“…The various mechanisms of the pulses reported in passively MLFLs, such as CS, , large-energy solitons pulse, , dissipative solitons, − HML, , and soliton rain , indicate that passively MLFL is an ideal platform for studying the NLO of SA and soliton dynamics. , As an operation state between continuous wave (CW) and CS pulse, soliton rain is typically characterized by the fact that there will be a continuous spontaneous formation of new soliton pulses in the noise and drift at an almost constant rate until eventually converging to the cohesive soliton phase . Large-energy pulses typically have pulse widths on the order of nanoseconds, so their pulse energies are much higher than the energy limit of CS.…”

Germanene (Ge), as one kind of Xene, possesses excellent nonlinear optical and photoelectric properties. In this paper, Ge nanosheets (Ge-NSs) were prepared and utilized as saturable absorbers in an Er-doped fiber laser to successfully achieve soliton rain and large-energy pulse modulation. The operation of a soliton rain pulse was achieved at a pump power of 34 mW. The number of drifting solitons gradually increases with increasing pump power. By increasing the pump power to 90.8 mW and adjusting the polarization controller, the second and third harmonic soliton rain phenomena can also be produced. Stable large-energy pulse output was obtained at pump powers ranging from 125.3 to 585.2 mW, with a maximum pulse energy of 12.75 nJ and a maximum pulse width of 120.08 ns. The research results show that Ge-NSs can be used as excellent optical modulators for studying multiple soliton dynamics and generating large-energy pulses, which have great potential for applications in nonlinear photonics.

“…In 2019, Fu et al carried out research on high-energy fiber laser and obtained soliton mode-locked operation with the maximum single-pulse energy of 20.4 nJ [ 20 ]. In 2021, Zhu et al realized a mode-locked fiber laser based on Cr 2 Si 2 Te 6 as SA and obtained maximum average output power of 85.54 mW at the pump power of 1659 mW and single-pulse energy of 53.03 nJ [ 21 ]. A variety of SAs have been developed to fabricate high-energy pulsed fiber lasers.…”

High-energy Er-doped fiber laser with high conversion efficiency is reported, which is mode-locked by a germanium telluride (GeTe)-based saturable absorber (SA). By adjusting the direction of the polarization controller (PC), a high-energy pulse with a central wavelength of 1533.1 nm and a fundamental repetition frequency of 1.58 MHz is achieved. Under the pump power of 450.1 mW, the maximum average output power is 50.48 mW, and the single-pulse energy is 32 nJ. It is worth noting that the optical-to-optical conversion efficiency has reached about 11.2%. The experimental results indicate that GeTe performs excellently as SAs for obtaining mode-locked fiber lasers and plays an extremely important role in high-energy fiber lasers.
