以1560 nm 的掺 Er3+石英光纤激光器作为泵浦源，在 Tm3+掺杂的碲酸盐微结构光纤中实现了2μm的激光输出。采用棒管法拉制出了纤芯由6个空气孔包围的微结构光纤，选取了2.8 cm 的微结构光纤，研究了其激光性能，获得了9 mW 波长为1872 nm 的激光输出，激光的斜效率为6.53%，激光阈值为200 mW。研究结果表明，所制备的 Tm3+掺杂碲酸盐微结构光纤可用于制作紧凑型2μm 光纤激光器。

We investigated the ~ 2 μm lasing performance of Tm3 + doped tellurite microstructure fi-ber pumped by an Er3 + doped silica fiber laser operating at 1 560 nm. The microstructure fibers consisting of a solid core surrounded by six air holes were fabricated by using a rod-in-tube method. A maximum unsaturated power of 9 mW laser operating at ~ 1 872 nm was obtained in a Tm3 +doped 2. 8 cm long microstructure fiber with the slope efficiency of ~ 6. 53% and the threshold pow-er of ~ 200 mW. The results indicate that the Tm3 + doped tellurite microstructure fiber is a promis-ing material for the compact 2 μm fiber laser.
