The acoustic modes of diamond not only are of profound significance forstudying its thermal conductivity, mechanical properties and opticalproperties, but also play a determined role in the performance ofhigh-frequency and high-power acoustic wave devices. Here we report the bulkacoustic waves (BAWs) and surface acoustic waves (SAWs) of single crystaldiamond by using the angle-resolved Brillouin light scattering (BLS)spectroscopy. We identify two high-velocity surface skimming bulk waves, withsound velocities of 1.277x10^6 and 1.727x10^6 cm/s, respectively. Furthermore,we conduct the relationship among the refractive index, incident angle and thevelocities of BAWs propagating along an arbitrary direction. Our results mayprovide a valuable reference for fundamental researches and devices engineeringin the community of diamond-based acoustic study.
