“…Due to the operating bandwidth of the TBPF, the Qswitching range was limited to between 1895 nm to 2050 nm. However, Feng et al (2018) [55], Wang et al (2018) [56] and Hao et al (2019) [57] had previously demonstrated Q-switched outputs at 1064 nm, 1300 nm, and 2730 nm using MXene based SAs. As such, it is quite likely that Q-switching beyond 1895 nm to 2050 nm can also be achieved from the proposed cavity of this work through the use of a TBPF with a wider pass-through bandwidth.…”

MXenes have recently gained significant research interest due to its graphene-like structure that allows for a multitude of applications such as electronics, batteries and optics to be realized. In this work, stable Q-switched pulses are passively obtained from a thulium-doped fiber laser using an MXene Ti 3 C 2 T X coated microfiber as a saturable absorber (SA). The generated pulses have center lasing wavelength 1976 nm with a pulse repetition rate and pulse width ranging between 16 kHz to 59 kHz and 13 µs to 2.4 µs respectively. The generated pulses can be tuned over a wavelength range of 155 nm from 1895 nm to 2050 nm. The MXene based SA has signficant potential for generating pulsed laser outputs that will find uses in the areas of sensing, medicine and spectroscopy around the 'eye safe' 2 µm region.

“…The MXenes SAs demonstrated the highest average output power of 150 mw when compared to other visible Qswitching lasers based on low-dimensional SAs. A variety of gain mediums were employed to obtain different wavelength outputs of Ti 3 C 2 T x SAM Q-switching laser, which include Nd:YAG, [147] YVO 4 /Nd:YVO 4 /YVO 4 , [149] Ho,Pr:LLF, [150] Er:CaF 2 -SrF 2, [152] Pr: LiYF 4, [155] Er: ZBLAN, [161] Ho: YLF, [157] and Gd:CaF 2 . [158] These gain mediums provide a broad operating wavelength range of 600-3000 nm with Ti 3 C 2 T x SAM Q-switching laser.…”

The family of 2D transition metal carbides, nitrides, and carbonitrides (MXenes) has attracted an enormous amount of attention due to their tunable optical, electronic, electrochemical, and mechanical properties. Recently, a new branch of MXenes materials research has emerged that is exploring and engineering the intrinsic optical response of MXenes, resulting in compact nonlinear optical (NLO) devices. As a novel 2D materials system, MXenes not only exhibit common advantages of classical 2D materials for NLO applications but also demonstrate their unique superiority, such as high yield and scalable synthesis, good stability, switchable NLO response, etc. Here, a fundamental overview of MXenes nonlinear optics is provided, covering everything from MXenes synthesis to linear and NLO properties and NLO applications. The synthesis method and its influence on the MXenes structures and morphology are discussed, which dominated the linear optics of MXenes. Then, the third‐order NLO properties and carrier dynamics of MXenes, from basic theory to experimental results, are elaborated. Their NLO applications, including ultrashort laser pulse, single‐frequency laser generation, all‐optical phase modulation, wavelength modulation, and passive photonic diodes, are also highlighted. Finally, the current challenges and an outlook for future MXenes NLO research are proposed.

“…However, the majority of existing reports on Ti 3 C 2 T x twodimensional film used as a SA in passively Q-switched lasers focus on wavelengths at 1.06 µm, 1.3 µm, 2.73 µm, and 3 µm. [16][17][18][19] Few of the reports are about Ti 3 C 2 T x used as an SA for passively Q-switched lasers at 1123 nm.…”

We report a high repetition frequency, high power stability and low laser noise laser-diode (LD) end-pumped Nd: YAG ceramic passively Q-switched laser at 1123 nm based on a Ti3C2T x -polyvinyl alcohol (PVA) film as a saturable absorber (SA). A Brewster polarizer (BP) and a birefringent crystal (BC) are incorporated to enable frequency selection and filtering for the passively Q-switched 1123 nm pulsed laser to improve the power stability and reduce the noise. When the pump power is 5.1 W, an average output power of 457.9 mW is obtained, corresponding to a repetition frequency of 1.09 MHz, a pulse width of 56 ns, a spectral line width of 0.65 nm, a power instability of ±0.92%, and a laser noise of 0.89%. The successful implementation of the “Ti3C2T x -PVA film passively Q-switching” combined with “frequency selection and filtering of BP + BC” technology path provides a valuable reference for developing pulsed laser with high repetition frequency, high stability and low noise.
