Acoustic transients generated by high voltage pulses in longitudinal KDP modulator crystals were investigated. Photographic method has been developed to visualize the acoustic waves. The experiments directly demonstrate the piezoelectric acoustic wave generation, the acoustic wave propagation, the reflexion, diffusion and diffraction of acoustic waves and the interaction of acoustic waves with crystal imperfections. From the experimental results the velocity of shear waves and the related elastic constant can be evaluated.
