Two-dimensional (2D) materials have attracted extensive interests due to their wide range of electronic and optical properties. After continuous and extensive research, black phosphorus (BP), a novel member of 2D layered semiconductor material, benefit for the unique in-plane anisotropic structure, controllable direct bandgap characteristic, and high charge carrier mobility, has attracted tremendous attention and successfully applied in ultrafast pulse generation. This article, which focuses on near-infrared ultrafast laser demonstration of BP, present discussion of preparation methods for high quality BP nanosheet, various BP based ultrafast lasers in the spatial/temporal domain, and the future research needs.
二维（2D）材料因其广泛的电子和光学特性而引起了广泛关注。经过持续广泛的研究，黑磷（BP）作为二维层状半导体材料的一个新成员，由于其独特的面内各向异性结构、可控的直接带隙特性以及高载流子迁移率，已引起了极大关注并成功应用于超快脉冲产生。本文聚焦于黑磷的近红外超快激光演示，讨论了高质量黑磷纳米片的制备方法、空间/时间域中各种基于黑磷的超快激光器以及未来的研究需求。
