ABSTRACT:
Apparatus for scanning a continuous wave Nd:YAG laser beam across a moving strip of grain oriented silicon steel having an insulative coating to subdivide the magnetic domains of the strip to improve core loss without damage to the insulative coating. The laser beam is scanned by a multiple-faced rotating mirror and focused onto the strip surface by a flat field lens and cylindrical lens to produce a scan line of narrow width having the required irradiation energy, dwell time and line spacing at the surface of the moving strip.
