Abstract
According to one implementation, a laser peening processing apparatus includes a laser oscillator and an irradiation system. The laser oscillator oscillates a laser light. The irradiation system condenses the laser light with a lens and irradiates a workpiece with the condensed laser light. The irradiation system irradiates the workpiece with the laser light in a state where the workpiece has been exposed in an atmosphere without interposed liquid. Furthermore, according to one implementation, a laser peening processing method includes producing a product or a semi-product by laser peening processing of the workpiece using the above-mentioned laser peening processing apparatus.
