<p>A laser shock processing method for evaporating a light absorbing material (112) by irradiation of laser light and for applying a shock to a metallic workpiece (111) by utilizing an increase in pressure due to evaporation of the light absorbing material, comprises the steps of: mounting a light absorbing film (112), which is formed in such a manner as to have a predetermined thickness and is made of a light absorbing material for absorbing laser light, on a surface of the metallic workpiece (111); mounting a light transmitting member (113) on the light absorbing film (112); and irradiating the light absorbing film with a laser light pulse through the light transmitting member, wherein the absorbing film (112) is wound on a reel (115) in such a manner that it can be unwound therefrom if necessary. <IMAGE></p> |
