摘　　要：波长在3μm附近的中红外Er掺杂的氟化物(Er:ZBLAN)光纤激光器凭借其良好的光束质量、体积小、可盘绕、易于实现等优势广泛应用于工业、医疗、军事等领域。本文主要介绍了基于Er:ZBLAN光纤激光器的发展现状,讨论了它们在发展中遇到的技术难题,总结并展望了其未来的发展方向。针对目前研究现状,提出多级放大将会是进一步提升3μm Er:ZBLAN光纤激光器单路激光功率的方法。为了突破单路激光的功率极限,将其与光纤合束技术融合将会成为未来的一个研究方向。Mid-infrared Er:ZBLAN fiber laser emitting at the wavelength of 3 μm is widely used in industry, medicine, military and other fields due to its advantages such as good beam quality, small size, coiling-ability and easy realization. In this paper, the development status of Er:ZBLAN fiber laser is introduced. The technical difficulties encountered in the development of Er:ZBLAN fiber laser are discussed. Moreover, their future development directions are also summarized and prospected. According to the current research situation, it is proposed that multi-stage amplification will be a method to further improve the single laser power of 3 μm Er:ZBLAN fiber laser. In order to breakthrough the power limit of single laser, the integration of single laser and fiber beam combination technology will become a research direction in the future.
