MXenes是最近开发的二维（2D）材料，包括2D过渡金属碳化物、氮化物和碳氮化物，并且具有可变的性质。特别是，MXene的手风琴状结构具有高度可调谐和可剪裁的光电特性，这表明它们可以应用于宽带光学器件。然而，由于合成工艺复杂，MXene的可饱和吸收体（SA）性能至今尚未得到充分探索和广泛应用。在这篇文章中，少层MXene纳米片的表征已经系统地进行。此外，MXene色散被用作SA没有任何聚合物和应用在一个紧凑的集成掺铒光纤激光器在1.5 μ m，以产生一个强大的，高平均功率脉冲。在平均输出功率为40 mW的条件下，该脉冲激光器的最小脉冲宽度为1.37 μ s，脉冲能量为305 nJ，高于已有的实验结果。考虑到MXene Ti3C2Tx在产生大能量脉冲方面的优点，我们的工作可能是优化光子器件的一种新方法。
MXenes, recently developed two-dimensional (2D) materials, comprise 2D transition metal carbides, nitrides, and carbonitrides and have variable properties. In particular, accordion-like structures of MXene have highly tunable and tailorable optoelectronic properties, which indicates that they can be applied in broadband optical devices. However, due to the complex synthesis process, the saturable absorber (SA) properties of MXene have not been fully explored and widely applied until now. In this article, the characterization of few-layer MXene nanosheets has been systematically performed. Furthermore, the MXene dispersion is utilized as a SA without any polymer and applied in a compact integrated Er-doped fiber laser at 1.5 mu m to generate a robust, high average power pulse. The proposed robust pulsed laser has minimum pulse width of 1.37 mu s under average output power of 40 mW and the corresponding pulse energy is 305 nJ, which is higher than previous experimental results. Considering the merits of MXene Ti3C2Tx, in the generation of large energy pulses, our work could be a novel method to optimize photonic devices.
