Abstract

A laser processing apparatus includes a laser oscillating mechanism for emitting pulsed laser beams. The laser oscillating mechanism includes a group setting section for establishing the number of pulsed laser beams to be applied to a workpiece until a time after which melted debris produced by the pulsed laser beams applied to the workpiece is solidified, and assigns the pulsed laser beams to a group, under conditions that, within a period of time which is shorter than a period of time in which the melted debris is produced, and within a period of time after which a plasma generated by the pulsed laser beam becomes extinct, a next pulsed laser beam is applied to the workpiece to sustain the plasma uninterruptedly to break growing debris, and a time interval setting section for establishing a time interval between the group and another group adjacent thereto.
