Laser peening is the process of hardening or peening metal using a powerful laser. Laser peening can "impart a layer of residual compressive stress on a surface that is four times deeper than that attainable from conventional peening treatments."[1] Laser peening is often used for the hardening of cutting and forming tools, and the laser is usually handled by an industrial robot.[2]
