| description | A laser machining method for cutting or cutting grooves on a workpiece using an apparatus having an X-Y table for mounting the workpiece, a laser source emitting a continuous wave or a quasi-continuous wave laser beam, modulator forming a pulsed laser beam by a high-speed modulation of the continuous wave or quasi-continuous wave laser beam, and an optical system capable of converging the pulsed laser beam on the workpiece, wherein the method comprising cutting with the pulsed laser beams along a locus including a portion where the moving speed of the X-Y table is decreased, and the pitch of holes machined with said laser pulses is kept constant by adjusting the intervals between successive said laser pulses in accordance with the moving speed of said workpiece, the method further comprising increasing the pulse widths of the laser pulses in accordance with the decrease in moving speed of the X-Y table in the portion where the moving speed of the X-Y table is decreased. |
