Abstract
In a laser machining apparatus in which one laser beam is split into two laser beams by first polarizing means, one of the laser beams propagates by way of a mirror, another laser beam is scanned in two axial directions by a first galvanoscanner, and the two laser beams are guided to second polarizing means and then scanned by a second galvanoscanner to process a workpiece, an optical path is configured so that the laser beam which is transmitted through the first polarizing means is reflected by the second polarizing means, and the laser beam which is reflected by the first polarizing means is transmitted through the second polarizing means.
