摘　　要：分布式布拉格反射镜(DBR)线性腔结构因其腔长较短、结构简单,具有工作稳定、不易跳模、抗干扰能力强和易于实现全光纤化的优点。因此,DBR单频光纤激光器是目前实现单频激光输出的主要选择。本文首先回顾了DBR窄线宽光纤激光器自诞生以来发展的历程,介绍了在实际应用需求的牵引下催生出的新技术和新思路。然后,归纳了近年来DBR窄线宽光纤激光器的国内外研究进展。最后,讨论了当前面临的问题与挑战,并对未来发展趋势进行了展望。Distributed Bragg reflection(DBR)linear cavity structure has the advantages of stable operation,less mode hopping,strong anti-interference ability and easy realization of all fiber due to its short cavity length and simple structure.Therefore,the DBR single frequency fiber laser is currently the main choice for realizing single frequency laser output.Firstly,the development of DBR narrow linewidth fiber laser since its inception is reviewed,and the new technologies and ideas that generated as a result of the demand for practical application are introduced.Then,the typical research progress of domestic and international research on DBR narrow linewidth fiber lasers in recent years is summarized.Finally,the current problems and challenges are discussed,and the future development trends are prospected.
