Abstract：
 This invention belongs to photoelectricity technique field and relates to a stimulated Brillouin scattering suppression control method used in optical fibre parametric amplification of pumping source, wherein, to include the frequency shifting optical fiber circular cavity with light source as processor for optical fibre parametric amplification of pumping source and in same time to adjust the filter wave peak of tuning light filter in the cavity to the wavelength of input light with single frequency; to get multiple frequency output through multiple frequency shifting with slowly decreasing range in the output end of the circular cavity simultaneously with free oscillation output formed from self-radiation when the gain and loss of the input light with single frequency in the cavity is getting close;and to adjust power of input light with single frequency to let the operation in the cavity stop at free oscillation critical point; to use the obtained output light with multiple frequency as pump light of optical fiber parametric amplification or optical fiber parametric oscillating apparatus.
