Abstract: By means of measuring the frequency shifts, a series of physical quantities can be accurately calculated by Brillouin scattering like sound velocity, elastic constants, elasto-optical coefficient, refractive index, bulk modulus, polarizability and adiabatic equation. On the basis of these quantities, we can get material’s phase transitions, structures and the information of earth and planetary interior. In this article, the research progress is reviewed on the following aspects: Brillouin scattering, applications of Brillouin scattering earth science under different temperatures and pressures. At the last of this paper, the further prospect was discussed.

Key words: brillouin scattering; sound velocity; elastic constant; earth material; high temperature and high pressure
