A shock wave produced by laser pulse interaction with a metallic target immersed in water was studied by methods of holographic interferometry and shadowgraphy. The wave parameters -- velocity, pressure in front, compressed layer thickness -- were determined, the pressure profile was constructed. The dependence of shock wave parameters on incident laser radiation energy was used to develop a method for determination of energy threshold of material damage. As a result of the action of pulsed laser radiation on a metal target a shock wave is generated in surrounding media due to the different processes which take place in a thin surface layer of the target. These processes -- thermal expansion, explosive evaporation, optical breakdown -- become valid step-by-step with the laser radiation energy increase. This paper presents the results of experimental study of such waves produced in water via laser pulse action on the metallic target immersed into it.
