摘要： A laser cutting apparatus (10) includes a laser processing head (15) that receives a laser beam emitted by a laser oscillator (12) and that uses a spherical lens for converging the laser beam so as to cause the intensity distribution of the laser beam to have a caldera-like shape, in which the intensity of the laser beam is higher in a peripheral area than in a central area, at the position of a workpiece (20). Moreover, the laser processing head (15) radiates the laser beam whose focal position is displaced from the position of the workpiece (20) to the workpiece (20). Therefore, the laser cutting apparatus (10) performs an inversion on the laser beam by using the spherical aberration of the spherical lens. Consequently, with a simple configuration, a laser beam whose inner area and outer area are inverted at the position of the workpiece (2) can be generated, and the processing direction for processing the workpiece (20) is not limited.
