Abstract

We describe the method that allows us to give an estimation of the uncertainty on the frequency peak by Brillouin Light Scattering. It isthe speed of phonons in a material excited by a visible green 532 nm wavelength laser. We follow the Guide to the Expression of Uncertainty in Measurement to obtain a first estimation of the speed of the phonons at 5 % at 2 sigma.
