To study the high pressure dynamic response characteristics of metal alumi‐num ,the high pressure sound velocity experiment was carried out with laser driven shock compression loading method and window‐VISAR method .The small scale target structure was designed according to the simulation result of the key physical process for high pressure sound velocity .The interference signals of the shock loading and rarefac‐tion process were successfully observed by streak camera .The longitudinal wave sound velocity of metal aluminum sample is well consistent with the theoretical result .
