摘　　要：随着激光雷达、引力波探测和光学原子钟等新技术的兴起和研究的不断深入,光学精密测量覆盖的应用领域的广度和深度都在拓展,传统自由运转的激光器其稳定性难以满足高精密测量的应用要求。超窄线宽、超低噪声和长期稳定的光源已成为该领域迫切追求的目标。光纤激光器具备结构紧凑、易于集成化和极限线宽窄等特点,通过噪声抑制和稳频技术输出超稳定、超窄线宽激光,近年来逐渐成为热点研究方向。本文从光纤激光器的噪声理论出发,介绍了光纤激光器的噪声来源、分类及测试方法,基于噪声理论,分类总结了光纤激光器强度噪声和频率噪声不同抑制技术的原理、发展历程及现阶段进展,并对窄线宽光纤激光器的发展趋势做了展望。With the rising and research deepening of new technologies such as laser radar,gravitational wave detection,and optical atomic clock,The breadth and depth of applications covered by optical precision measurement are expanding,the stability of the traditional free operation of the laser is difficult to meet the application requirements,ultra-narrow linewidth,low noise,and long-term stability of light source has become the urgent goal in this field.Fiber laser has the characteristics of compact structure,easy integration,and narrow limit line width.Through noise suppression and frequency stabilization technology,fiber laser can output ultra-high stability and ultra-narrow linewidth laser.In recent years,ultra-narrow line width fiber laser has gradually become a hot research direction.In this paper,starting from the theory of noise of fiber laser,the noise source,classification,and testing method of fiber laser are introduced,based on the theory of noise,the principle of different intensity and frequency noise suppression technology,development course,and the current progress of fiber laser are summarized,respectively,and the development tendency of narrow linewidth fiber laser is discussed.
