Abstract
An embodiment is to provide a laser light irradiation apparatus and a laser peening treatment method, by which even a member to be processed, existing in a narrow portion, can be easily processed by laser peening. The laser light irradiation apparatus 1 according to the embodiment includes: an optical fiber 2 through which laser light is guided; a condensing lens 3 that is placed on one end of the optical fiber, the condensing lens and the optical fiber defining the light path of the laser light; a guide 4 that retains the optical fiber; and a movement mechanism 5 for changing the position of the optical fiber, wherein the light path of the laser light guided through the optical fiber is emitted at an angle changed to more than 0° and less than 90° with respect to the central axis of the optical fiber by the condensing lens.
