ABSTRACT:
A machine manipulates a laser beam substantially transversely across a moving sheet of flat or curved material. This machine includes a rotating optical system which focuses and moves an elongate beam spot across the moving sheet of flat or curved material, at a high rate of speed. In methods of applying these instruments to produce reductions in watt loss in coated ferromagnetic sheet without damage to the coating, the speed of laser scanning, S.sub.2 (inches/minutes), and the incident power, P (watts), of the beam are selected such that the function, PS.sub.2.sup.-1/2 is between about 0.1 to about 7.
