Abstract:
In removal processing using a pulsed laser beam, processing deviation occurs in the depthwise direction to cause a processing error in a predetermined removal shape.A first pulsed laser beam L1 is a pulsed laser beam having a wavelength that exhibits transmittance to a workpiece 6, and a second pulsed laser beam L2 is a pulsed laser beam having a wavelength that exhibits absorption to the workpiece 6. The first pulsed laser beam L1 is focused into the workpiece 6, and a focal point P1 of the first pulsed laser beam L1 is scanned along the outline of a predetermined removal region R1 to form a modified portion 6A along the outline of the predetermined removal region R1. Next, removal processing is performed by scanning the second pulsed laser beam L2 in a region enclosed by the modified portion 6A.
