Laser hardening or laser peening involves the interaction of an intense laser pulse with the absorbing surface of the metal under water. An ablation shockwave is produced which, depending on the geometry and laser beam area, induces residual stress on the surface layer of the metal. The aim of the research work presented in this thesis is to investigate optically the laser peening method by analysing the ablation shock waves using high-resolution Schlieren photography.
