“…In the InF3 fiber, broadband mid-infrared SC extending to the long wavelength region mainly contributed to the soliton self-frequency shift. The physical mechanism of the SC generation in the InF3 fiber was discussed in detail in Ref [6]. Next, we turned on the 976 nm LD and increased its power gradually on the condition that the pump power of 793 nm was still 2.94 W. Intense amplification of the spectrum around 2.8 μm was observed.…”

“…The whole SC laser source is comprised of a broadband seed laser and an EDZFA.The broadband seed laser is similar to that reported in Ref. [6], which consists of a 2 um figure-9 NLP mode-locked fiber laser, a thulium-doped fiber amplifier, and a piece of InF3 fiber. The NLP seed laser has long fibers at its linear branch, including ~100 m standard single mode fiber (SMF-28) and ~100 m dispersion compensation fiber (UHNA4, Nufern), to improve its performance of shorter pulse duration and lower pulse duty cycle Ref.…”

“…Another common technical route to obtain a mid-infrared SC is pumping fluoride fibers with amplified conventional ~2 μm mode-locked ultra-short pulse [5] . Recently, we have proposed another efficient pumping proposal for all-fiber mid-infrared SC generation, i.e., a type of low repetition rate noise-like pulses (NLP) as the pulse seed [6] .…”

An all-fiber mid-infrared enhanced supercontinuum laser source, spanning from ~2 μm to ~4.2 μm, was demonstrated in an erbium-doped ZBLAN fiber amplifier. A 2 μm low repetition rate noise like-pulse mode-locked fiber laser was adopted as the pulse seed for the system. Thanks to using a new-type homemade silica-fluoride fiber pump combiner, the 2.8 μm pulses in the supercontinuum were amplified in the erbium-doped ZBLAN fiber amplifier with all-fiber structure. Due to soliton self-frequency shift, long wavelength components were generated and a 1.4 W mid-infrared enhanced supercontinuum with up to 97% of the power beyond 2.7 μm was obtained in the erbium-doped ZBLAN fiber. This research demonstrated a compact and simple in-amplifier mid-infrared supercontinuum generation with all-fiber structure.

“…Because of the broad temporal width, NLPs can operate in the high-pulse-energy region and allow a further pulse energy scaling through fiber amplification without any pulse shaping, [19] rendering them attractive for applications such as supercontinuum generation, materials processing, and low-coherence spectral interferometry. [20][21][22][23] Moreover, the complex dynamics and intrastructure of NLPs make them a good platform for studying extreme events like optical rogue wave. [24] NLPs were first reported by Horowitz et al in a mode-locked erbium-doped silica fiber laser, of which the generation was attributed to the fiber birefringence combined with a nonlinear transmission element and the gain response of the amplifier.…”

Noise‐like pulses (NLPs) are becoming increasingly attractive for a variety of applications such as supercontinuum generation, materials processing, and low‐coherence spectral interferometry. Related research in the near‐infrared region is extensive, yet few studies have been reported in the mid‐infrared (MIR) region. Herein, a systematic investigation of MIR NLPs is made for the first time. An approach is presented by exploiting a polarization‐maintaining fluoride fiber in the mode‐locked oscillator to cause a polarization‐dependent delay between the orthogonal‐polarized components of intracavity circulating pulses, thus generating a series of ultrashort pulses which will eventually form a stable wave packet, namely, NLP. Numerical simulations based on the extended coupled nonlinear Schrödinger equations predict the generation of NLPs, and reveal key aspects of the pulse evolution. Experiments yield linearly polarized NLPs at 2.8 μm with a maximum average power of 498 mW and a spike width of 4.3 ps, corresponding to a pulse energy of 12 nJ. The experimental results are in good agreement with the simulation results. This work constitutes a major step toward the development of MIR ultrafast fiber lasers with NLPs output.

Herein, the efficiently high‐power pulsed Raman lasers with wavelength above 2.1 μm are experimentally demonstrated relying on the stimulated Raman scattering. A tailored high‐power noise‐like pulse (NLP) fiber laser system centered at ≈1953 nm with a maximum output power of ≈10.9 W is served as the pump source. By directly pumping a section of highly Ge‐doped silica fiber, the first pulsed Raman laser (centered at≈2139 nm) and the second pulsed Raman laser (centered at ≈2353 nm) with maximum output powers of ≈3.8 and ≈0.25 W are obtained, respectively, which represent the highest output powers of NLP at these wavelength regions, to the best of knowledge. Moreover, a high spectral purity of ≈94.3% of the first Raman laser is obtained, which indicates the significantly potential application of NLP in pulsed Raman laser. The midinfrared NLP fiber laser source will have potential applications in transparent polymer materials processing and midinfrared spectroscopy.
