Being a new class of two dimensional (2D) metal carbides, borides, and nitrides, MXenes comprise one of the largest families of 2D nanomaterials that provide huge possibilities in photonics, electronics, and energy, Particularly, MXenes are discovered recently as alternatives to conventional saturable absorbers (SAs), such as carbon nanotube and graphene, which are used for short laser pulse generation. The high saturable absorption, astounding modulation depth, flexible bandgap tunability, and high electron density near Fermi level are the main features that make MXenes excellent candidate materials for SAs. Herein, this review summarizes the recent development on synthesis and characterization of the MXene, with focus on the nonlinear saturable absorption and the application of the MXene SA in mode‐locked fiber lasers. The emerging issues and challenges associated with MXene based SAs, as well as future perspectives of the reviewed topic are also discussed.

“…Since Richardson et al observed square pulses in a mode-locked fiber laser in 1991 [6], researchers began to study square pulses. There are different explanations for the formation of square pulses, one of which is dissipative soliton resonance (DSR) [7]. Under the DSR mechanism, the width and energy of the square pulses increase monotonically with the increase of the pump power without wave breaking, and the peak amplitude is almost unchanged [8,9].…”

In this paper, a dual-wavelength square pulses fiber laser with tunable pulse width based on nonlinear polarization rotation and nonlinear effect was studied. The fiber laser containing a 1050-m highly nonlinear fiber operated at central wavelengths of 1533 nm and 1569 nm and the repetition rate was 194.7 kHz. While the polarization state of the laser was unchanged, the pump power was increased from 100 mW to 300 mW, and the pulse width was extended from 163.6 ns to 558.2 ns. In this process, the maximum energy of a single pulse was 8.57 nJ. The simple, compact square pulse dual wavelength fiber laser with tunable pulse width can meet great potential for applications.

Ultrafast polarization‐maintaining fiber lasers (UPMFLs), with superior optical performance and high immunity to environmental disturbances, are highly preferable in a variety of industrial and scientific applications such as high‐precision micromachining and biomedical imaging. Especially, the utilization of PM fibers endows the laser intrinsic stability, thereby enabling the construction of robust and low‐noise optical frequency comb systems. To meet more demanding application challenges, continuous efforts have been invested in the design and fabrication of UPMFLs, aiming to reach unprecedented levels of various pulse parameters, that is, to achieve shorter pulse duration, higher or lower repetition rate, and higher pulse energy. This review presents a detailed overview of different passive mode‐locking techniques for pulsed operation and the most significant achievements in UPMFLs. Representative advances at 1.0, 1.55, and 2.0 µm spectral regions are presented and summarized. The state‐of‐the‐art lasing performance is application‐oriented, and conversely, optical improvements in all‐PM pulsed lasers promote emerging applications, which are also discussed and analyzed. How to overcome the bottlenecks of UPMFLs in terms of pulse duration, repetition rate, emission wavelength, and pulse energy to make them powerful tools for physical, medical, and biological applications remains challenging in the future.
