摘　　要：扫频光纤激光器在光纤传感、生物医学以及光谱学等领域有着极其重要的应用价值,扫频光纤激光器的中心波长、扫频速度、扫频范围、输出功率等参数决定了光纤传感系统和生物成像系统的性能,因此,对扫频光纤激光器及其各项性能参数的研究具有重要意义。目前研究的扫频光纤激光器主要可以分为两大类:一类是基于色散调制扫频光纤激光器,另一类是基于光学滤波器的扫频光纤激光器。主要介绍了基于光学滤波器的扫频光纤激光器的研究进展和在各项性能参数上的研究成果。同时,指出其存在的问题并对扫频光纤激光器的发展进行展望。Frequency-swept fiber lasers have extremely important application values in the fields of fiber sensing,biomedical,and spectroscopy. The parameters such as the center wavelength,sweep speed,sweep range,and output power of the frequency-swept fiber laser determine the performance of the fiber sensing system and the biological imaging system. Therefore,it is of great significance to study the frequency-swept fiber laser and its various performance parameters. The frequency-swept fiber lasers currently studied can be divided into two major categories,one is based on dispersion-modulated frequency-swept fiber lasers,and the other one is based on optical filters. This article mainly introduces the research progress of the frequency-swept fiber laser based on the optical filter and the research results on various performance parameters. At the same time,it points out its existing problems and prospects the development of frequency-swept fiber lasers.
