把光纤置于谐振腔内,利用光纤中的布里渊增益就构成光纤布里渊激光器。布里渊环形激光器由于具有线宽窄、频率稳定、增益方向敏感等优点成为国内外研究的热点。介绍了该种激光器产生的基础——受激布里渊散射理论,对布里渊环形激光器的研究进展情况进行了综述,介绍了各种布里渊环形腔结构的特点,最后探讨了该类激光器发展过程中存在的技术问题及其发展前景。 Put the optical fiber in the resonator, make use of the Brillouin gain in the optical fiber to make the fiber Brillouin laser. Brillouin ring laser has become a hot research field at home and abroad due to its advantages of narrow linewidth, stable frequency and sensitive gain direction. The basis of this kind of laser, the theory of stimulated Brillouin scattering, is introduced. The research progress of Brillouin ring laser is reviewed. The characteristics of various Brillouin ring cavity structures are introduced. Finally, Technical Problems and Development Prospects of Laser Development.
