Brillouin backscattering spectra for PMMA, fused silica, and soda lime glass

This data set contains Brillouin backscattering spectra used in publication "Accuracy of simultaneous refractive index and phonon velocity estimation using Brillouin backscattering in the platelet geometry". The ZIP archive contains text files that contain the raw Brillouin spectra presented as two columns: 1/ frequency in GHz 2/ photon count.
