Intensities of Hard and Soft Brillouin peaks of the bone, reported in a Cartesian plane (a) can be used to determine the average ratio of squared Pockels coefficients (r) and filling factors \(R = I_{HARD}^{*} /I_{HARD}^{f}\). (b) The whole set of pairs of \(I_{SOFT}\) and \(I_{HARD}\) Brillouin intensities obtained from our sample (black dots) with the linear interpolation (red line) whose angular coefficient gives r = 0.21 . In the inset, the distribution of filling factors obtained by Eq. 3.
