Abstract
A laser beam application unit of a laser processing machine includes a laser oscillator that emits a laser beam, an fθ main lens that focuses and applies the laser beam which has been emitted from the laser oscillator, to a workpiece held on a holding table, a scan unit that is arranged on an optical path between the laser oscillator and the fθ main lens, scans the laser beam, and guides the resulting scanned laser beam to the fθ main lens, and an fθ sub-lens that is arranged on the optical path between the laser oscillator and the scan unit and converts the laser beam from parallel light into diffused light.
