摘要: In order to measure the Brillouin frequency shift (BFS) of medium, this paper proposes a method using mixtures in two-cell stimulated scattering system, which uses medium be measured as amplifier and mixture generator medium. The seed light from gains effective amplification ratio changes with mixing fraction. Only when BFS is equal that does obtain maximum ratio. has advantage independence wavelength incident light.
