With the development of Fiber Optical Communication System and Optical Fiber Sensing Technique, Brillouin fiber ring laser has been rapidly developed and widely used. In this paper, the research items of Brillouin fiber ring laser are reviewed from the developments of fiber and several optical fiber devices. The characteristics and the problems of Brillouin ring resonator are showed. As a major application of Brillouin fiber ring laser, the Brillouin fiber-optic gyroscope attractes the attention of the world. In comparison with the interferometric fiber-optic gyroscope, the length of fiber used in Brillouin fiber-optic gyroscope is much more shorter, and the signal processing system is greatly simplified. It has obvious advantages in realizing high-precision and miniaturization of gyroscope. Furthermore, the principle and technical features of Brillouin fiber-optic gyroscope are analyzed, and the technical problems and development prospects of Brillouin fiber-optic gyroscope are reviewed.
