Abstract
A device for laser heating the surface of a small diameter bore in a workpiece includes a workpiece holder, optics for focusing a laser beam and introducing the laser beam into a bore and directing the beam against the bore surface. The workpiece holder and workpiece are movable longitudinally and rotationally with respect to the optics in the bore, to permit the laser beam to move along the bore. A first fluid cooling circuit cools the workpiece holder and workpiece, a second fluid cooling circuit cools the optics in the bore. Shielding gas is introduced into the bore to shield the bore surface being heated.
