In order to overcome the low accuracy of velocity measurements by Brillouin scattering, we have tried to make use of the induced coherent phonons, which brings intense Brillouin scattering peaks. To induce phonons, we used a tilted ZnO film transducer developed in our laboratory. As a result, we obtained the intense Stokes peak in the silica glass sample which was much larger than that obtained from the thermal phonons. Because Brillouin scattering enables the simultaneous measurement of longitudinal and shear phonons velocities, this technique opens the new feature for the non-destructive elasticity measurement.
