| Abstract: | We described the generation,measurement of the shock wave used in laser shock processing and its propagation in the target. The changes of peak pressure depending on the laser power density were studied, The generation of plasma ring at the surface of the target in the water- confinement was explained. The influence of the laser wavelength and pulse duration upon the maximum pressure and the pressure duration were discussed. |

| Keywords: | laser shock processing shock wave confinement layer pressure pressure |
