In efficient laser peening, a high amplitude shock impulse is necessary. The shock impulse can be increased by confinement of the laser-produced plasma through the acoustic impedance of a plasma confinement layer. To perform efficient laser peening, it is necessary to select a plasma confinement medium with consideration to acoustic impedance. In this study, the effect of laser peening is examined on the acoustic impedance of a plasma confinement medium.
