Abstract

High power laser bean can give rise to nonlinear change in the distribution of acoustic wave field and excite scattering Brillouin scattering (SBS) in water. At present, the uniform grating theory is used to analyze the spectral distribution of stimulated Brillouin scattering, which is inconsistent with the experiment. In this paper, three kinds of refractive index distribution model for reflection spectra were simulated by using the method of multilayer dielectric film, and the changes of the reflection spectra of different refractive index distribution models were analyzed.
