Patent ID: 7241967

Claim:
In a laser electrical wiring line cutting apparatus for cutting an electrical wiring line, the improvements comprising: a laser generator for generating a laser beam; an optical beam branching element for branching the laser beam generated by the laser generator into a plurality of branch beams; a beam condenser for condensing the branch beams branched by the optical beam branching element; a beam splitter element for splitting the laser beam generated by the laser generator into a plurality of beams, wherein the optical beam branching element is arranged for at least one split beam, and wherein the beam splitter element is a polarizing beam splitter; a variable retardation element disposed in front of the polarizing beam splitter for adjusting a polarization plane component ratio of the beam; and a suction mechanism for sucking in debris resulting from the cutting of the electrical wiring line at a focus point of at least one of the branch beams.
