Abstract

Brillouin scattering experiment has been carried out in the oxide crystal materials. A new wide-band component in the Brillouin spectrum has been observed in the SLAO sample. This completes typical the Brillouin spectrum in a solid state, where Rayleigh lines, stokes and anti-stokes optical signals are usually observed. This newly discovered spectral component is distributed uniformly in frequency, independent of the light power incident on a crystal and dependent on the light wavelength applied, what suggests absorption origin the phenomenon. The absorption-like channel in a scattering process should be interpreted as the sea of frequencies from where some specific values of Brillouin frequencies are seen.
