Abstract An experimental set-up is described for measuring, with high resolution, the hypersound-phase velocity and damping by means of Brillouin spectroscopy in the Giga-Hertz range. Measurements on water at 20°C between 3 and 6 GHz are presented showing no observable onset of dispersion in this region. Due to the high-power single-frequency HeNe-laser used and due to an effective collection of Brillouin-scattered light our experimental error is far smaller and the data are more reliable than in earlier investigations.
