A pulsed laser beam from a laser oscillator 10 is split into two by a beam splitter 13. The split laser beams are radiated by X-Y scanners 14 and 16 through working lenses 17 and 18 onto a work 20. Additionally on the work, the laser beams are swung in X-axis and Y-axis directions. These X-Y scanners simultaneously process a plurality of process regions which are divided and set on the work. |
