III Brillouin Spectrometer

Brillouin spectroscopy is widely used in remote sensing, materials science and biomedicine as a non-contact test for the acoustic, thermodynamic and viscoelastic characterization of materials. Brillouin spectroscopy detects inelastic scattered light with fluctuations in thermal density in acoustic modalities in solids and in liquid gases, derived from the inelastic interaction of incident light and acoustic phonons in materials. The spectral shift of this inelastic scattered light is generally in the subGHz range. Therefore, brillouin spectroscopy is a very weak signal, elastic scattering light (Rayleigh scattering or Michaelis scattering), stray light or sample reflected light can easily mask brillouin spectral signal, requiring spectrometers with very high spectral resolution, but also need high spectral contrast and high extinction ratio.
