Holmium (Ho3+)-doped fluorotellurite microstructured fibers based on TeO2-BaF2-Y2O3 glasses are fabricated by using a rod-in-tube method. By using a 1.992 μm fiber laser as the pump source, lasing at 2.077 μm is obtained from a 27 cm long Ho3+-doped fluorotellurite microstructured fiber. The maximum unsaturated power is about 161 mW and the corresponding slope efficiency is up to 67.4%. The influence of fiber length on lasing at 2.1 μm is also investigated. Our results show that Ho3+-doped fluorotellurite microstructured fibers are promising gain media for 2.1 μm laser applications.
基于TeO2-BaF2-Y2O3玻璃的掺钬（Ho3+）氟碲酸盐微结构光纤采用管中棒法制备。以1.992μm光纤激光器作为泵浦源，从一根27cm长的掺Ho3+氟碲酸盐微结构光纤中获得了2.077μm的激光。最大非饱和功率约为161mW，相应的斜率效率高达67.4%。还研究了光纤长度对2.1μm激光发射的影响。我们的结果表明，掺Ho3+氟碲酸盐微结构光纤是用于2.1μm激光应用的有前途的增益介质。
