Abstract: A laser processing machine including: a laser source that emits a laser beam; a polarization rotator unit; a beam rotator unit; a lens; and a controller, which apply the laser beam to a workpiece, the polarization rotator unit includes a wave plate and first actuator that rotates the wave plate, the beam rotator unit includes an optical system that adjusts an irradiation angle of the laser beam to the workpiece by making an incident laser beam eccentric to output and making the laser beam incident on the lens at a position eccentric from a central axis, a second actuator rotates the optical system, the lens condenses the laser beam on the workpiece, the controller controls a rotational speed ratio between the first actuator and the second actuator, and adjusts a polarized state of the laser beam by controlling the rotational speed ratio.
