The stimulated Brillouin fiber- optic ring laser is in widespread use,in order to determine length of the fiber- optic constituted the resonant cavity, the present research situation of stimulated Brillouin fiber- optic ring laser is introduced, the advantages and major application of the stimulated Brillouin fiber - optic ring laser are shown. A plan of the stimulated Brillouin fiber- optic ring laser is demonstrated,and threshold of the stimulated Brillouin scattering is investigated for the Brillouin fiber- optic ring laser by using non- linear theory,the relationship between threshold of the stimulated Brillouin scattering and length of the optical fiber in the resonant cavity, which is emulated,the values are in good agreement with those by experiments,which is useful as guidance for the design of the resonant cavity in the stimulated Brillouin fiber- optic ring laser.
