In this article, by shadowgraphical imaging technique, logged shock wave created from the plasma by laser pulse that is on the surface of an Aluminum sample is studied. Shadowgraphy as an effective and efficient method for recoding fast and efficient events like shock wave is based on changes in reflective index of the disordered area. For this purpose, in this article for shadowgraphy, two pulsed lasers are used _ one of them to ablation and creating plasma on the surface of sample and the other to create the shadow of shockwave. Recording the imaging of shock wave at different times and also the measurement of experimental results of the parameters related to position and speed of shock wave is studied.
