A a method for laser heating a surface formed by a circular bore extending in a workpiece along a longitudinal bore axis includes providing a holder for holding a workpiece; directing a laser beam into the workpiece bore; and providing a mirror in the workpiece bore for directing the laser beam against a portion of the surface to be heated. The workpiece is cooled adjacent the portion of the surface to be heated by the workpiece holder. The workpiece and mirror are moved relative to each other longitudinally back and forth along the workpiece bore axis and rotatably about the workpiece bore axis, to produce a preselected pattern of heated area on the workpiece bore surface.
