“…The higher molecule absorption in the 2-6 μm area makes the 2.0 μm ultrafast fiber laser sources useful for spectroscopy [1]. Ultrafast fiber lasers in the 2.0 μm region have several industrial and scientific uses in nonlinear frequency conversion, medical surgery, light detection and ranging (LIDAR), free space optical communications, and transparent material processing [2].…”

In this work, Graphene/Zinc Oxide (G/ZnO) nanocomposite was used to generate mode-locked pulses in Thulium/Holmium-doped fiber (THDF). The sol-gel method was used to synthesize the ZnO particles decorated graphene sheets. The G/ZnO nanocomposite solution was deposited onto the arc-shaped fiber that had been fabricated to act as the saturable absorber (SA) device. The nonlinear optical response of G/ZnO-based SA was investigated via the twin detection approach, in which it exhibits a modulation depth of 15.62 % and a saturation intensity of 0.031 MW/cm2. After incorporating the fabricated SA into the THDF laser cavity, mode-locked pulses were produced at a threshold pump power of 274.3 mW with a centre wavelength of 1895 nm, fundamental frequency of 11.82 MHz, and a pulse duration of 1.7 ps. The maximum average output power and single pulse energy were determined to be 1.39 mW and 117 pJ, respectively. The mode-locked pulses generated were exceptionally stable giving a signal-to-noise ratio (SNR) of 58.2 dB. According to the findings of the current research, it is anticipated that the G/ZnO-arc-shaped fiber-based SA has the potential to produce stable mode-locked lasers in the region of 2.0 µm which can many applications.

Mid‐infrared (mid‐IR) ultrafast lasers are widely employed in biomedicine, molecular spectroscopy, material processing, and nonlinear optics. With the improvement of fiber gain media and other fiber optical elements, low‐cost, compact, and high‐efficiency fiber lasers open up new opportunities for 2–4 µm pulse generations, which calls for a comprehensive review of their mode‐locking mechanisms, gain media, and fiber laser system performance. This paper, beginning with an overview of pulse‐generation technologies, reviews recent progress on 2–4 µm mid‐IR ultrafast fiber lasers, including Tm3+‐, Ho3+‐doped, Tm3+/Ho3+ codoped silicate fiber 2 µm lasers, and Er3+‐, Dy3+‐doped, and Ho3+/Pr3+ codoped ZBLAN fiber 2.5–4 µm lasers. Among them, the status of 2–4 µm ultrafast fiber lasers based on 2D material passive mode‐locking is emphatically discussed. Meanwhile, the novel advances on mode‐locking and gain fibers of mid‐IR ultrafast fiber lasers are explored. Furthermore, current and prospective applications of such laser systems are also introduced in detail. This review finally summarizes challenges associated with future development of mid‐IR ultrafast fiber lasers, which provides an outlook on how to achieve more desirable laser performance (e.g., higher average power, higher pulse energy, and longer emission wavelength) that can lead to more practical uses of such lasers.
