Abstract

The invention includes a laser processing method for processing a hidden surface of a workpiece, the hidden surface disposed within a recess having an opening. The method comprises inserting a reflective member into the recess and directing a pulse of coherent energy to reflect off of said reflective member and impact the hidden surface of workpiece to create a shock wave. Alteratively a surface of the recess may be modified to laser shock process the hidden surface.
