摘　　要：中红外波段激光光源在环境监测、材料加工、外科手术、军事等领域发挥重要作用。泵浦低损耗、高浓度Er^(3+)掺杂ZBLAN(Er∶ZBLAN)光纤是产生近3μm激光输出的主要手段之一,相较于其他同波段固态激光器,Er∶ZBLAN光纤激光器具有易集成、效率高,可采用激光二极管直接泵浦等优势,性能日渐提升的Er∶ZBLAN光纤激光器有望成为3μm波段最先发展成熟、走向应用的激光光源。本文主要介绍Er∶ZBLAN光纤激光器工作原理和发展现状,对三种不同的Er∶ZBLAN光纤激光器存在的问题进行分析和总结,最后对Er∶ZBLAN光纤激光器发展趋势进行展望。The mid-infrared(MIR)region plays an important role in the fields of environmental monitoring,material processing,surgery and defense.Currently,low-loss high-concentration Er^(3+)-doped ZBLAN(Er∶ZBLAN)fiber is one of the main promising gain media for 3μm MIR laser sources.Er∶ZBLAN fiber lasers have the advantages of being easily integrated,highly efficient and directly diode-pumped in comparison to other 3μm-class lasers.With improving performance,Er∶ZBLAN lasers are expected to reach maturity and commercialized at wavelength of near 3μm firstly.The working principle and status of Er∶ZBLAN fiber laser were briefly described in this paper,and the existing problems of three different Er∶ZBLAN fiber lasers were analyzed and summarized.Finally,the development trends were also prospected.
