MXene, as a novel 2D crystal material, possessing tunable bandgap, low optical attenuation and broadband nonlinear optical responses that may promote the fabrications of advanced electro-photonics devices has gathered remarkable attention recently. However, current investigations of 2D crystals for photonics devices suffer from the limitations of reproducibility, scalability, and compatibility. Inkjet printing is one of the powerful additive manufacturers that facilitate well-controlled, low-cost, scalable and small-footprint electro-photonics devices on myriad substrates. Herein, we directly inkjet printed MXene nanosheets in laser resonators with both fiber and free-space geometrics, and achieved extensive spectral band ultrafast laser operations from near- to the mid-infrared regime with pulse duration going to 100 femtoseconds. The demonstrations of versatile inkjet-printed devices based on MXene, while forthputting its distinct electro-optical properties, may allow the realizations of advanced MXene enable photonics devices shortly.

MXene作为一种新型的2D晶体材料，具有可调节的带隙，低的光衰减和宽带非线性光学响应，这些可能促进先进的电子光子器件的制造。但是，当前用于光子学设备的2D晶体研究受到再现性，可扩展性和兼容性的限制。喷墨印刷是功能强大的添加剂制造商之一，可促进在多种基材上进行可控，低成本，可扩展且占用空间小的电子光子学设备。在本文中，我们直接在具有纤维和自由空间几何形状的激光谐振器中喷墨印刷MXene纳米片，并实现了从近红外到中红外范围的宽谱带超快激光操作，脉冲持续时间达到了100飞秒。
