Abstract

Metal–organic framework (MOF) is a class of material that is highly porous and modular. Due to their unique properties, MOFs have found applications in gas storage, gas separation, sensing, and supercapacitors. [Zn2(H2L)2(1,2-Bis(4-pyridyl)ethene)4]n, zinc (Zn)-based MOF was used in this work to achieve mode-locked operation in a thulium/holmium-doped fiber laser due to its excellent optical absorption at a wavelength of 1925 nm. The saturable absorber (SA) was fabricated by drop-casting a mixture of Zn-MOF and isopropanol on an arc-shaped fiber. The center wavelength of the mode-locked laser is 1906.75 nm, with a maximum average output power of 3.251 mW. The fundamental repetition rate and the pulse width were 12.89 MHz and 1.772 ps. At the same time, the pulse energy and peak power were 252 pJ and 142 W, respectively. To the authors’ knowledge, this is the first time an MOF has been used for mode-locked pulse generation in a thulium/holmium-doped all-fiber laser. This work extends the use of MOF material as a saturable absorber for mode-locking applications in near-infrared fiber lasers.

Zn-MOF 作为掺铥/掺钬光纤激光器的可饱和吸收体

金属有机框架（MOF）是一类高度多孔和模块化的材料。由于其独特的性质，MOF 在气体储存、气体分离、传感和超级电容器等领域都有应用。[Zn2(H2L)2(1,2-Bis(4-pyridyl)ethene)4]n 是一种以锌（Zn）为基质的 MOF，由于其在 1925 nm 波长处具有极佳的光吸收特性，因此在本研究中被用于在掺铥/掺钬光纤激光器中实现锁模运行。可饱和吸收体（SA）是通过在弧形光纤上滴铸 Zn-MOF 和异丙醇的混合物而制成的。锁模激光器的中心波长为 1906.75 nm，最大平均输出功率为 3.251 mW。基本重复率和脉冲宽度分别为 12.89 MHz 和 1.772 ps。同时，脉冲能量和峰值功率分别为 252 pJ 和 142 W。据作者所知，这是首次在掺铥/掺钬全光纤激光器中使用 MOF 产生锁模脉冲。这项研究拓展了 MOF 材料作为可饱和吸收体在近红外光纤激光器锁模应用中的应用。
