摘要：

A new stimulated Brillouin scattering (SBS) configuration, SSS(Self Stokes Seeding) is presented to describe the influence of Stokes component in a pump light on SBS process. The fast Fourier transform is used to calculate the Stokes energy ratio which denotes the ratio of the energy of Stokes component to that of total pump laser: The coupled SBS equations is solved numerically and the SSS effects is evaluated. The study shows that when the pump laser is reflected normally by the back surface of the flat sample, the Stokes component plays an important role in SBS process, such as decreasing the initiation duration. The larger the Stokes energy ratio is, the shorter the initiation duration is.
