Abstract
In a laser shock peening process, the shape of the spot generated by the laser beam is changed on the fly. This is achieved, for example, by a masking device which is movable into and out of the path of the laser beam. Laser shock peening spots can consequently be shaped so as to avoid the spots overlapping an edge of the workpiece, or any other feature which may be damaged by the laser energy.
