PROBLEM TO BE SOLVED: To provide a processing device and a processing method which are capable of processing with simple structure and higher accuracy.SOLUTION: A processing device comprises an irradiation head and a control device. The irradiation head includes a laser pivot part, a light focus optical system, and a nozzle 38. The laser pivot part includes a first prism, a second prism, a first rotation mechanism, and a second rotation mechanism. The nozzle 38 includes a first nozzle part 77 and a second nozzle part 78. The control device controls rotation speeds of and a phase angle difference between the first prism and the second prism at least on the basis of a thermal influence layer of a workpiece W and a turn number of laser L. |
