Patent ID: 6984802

Claim:
A laser material processing apparatus for processing a workpiece in such a way as to separate one laser light beam into two laser light beams, comprising: a first polarizing means; a second polarizing means; a first galvano scanner; a second galvano scanner; and a plurality of mirrors, wherein the first polarizing means, the second polarizing means, the first galvano scanner, the second galvano scanner, and the plurality of mirrors are arranged so that: a first laser beam transmitted through said first polarizing means is reflected by said second polarizing means, and is conducted to said second galvano scanner; a second laser beam reflected by said first polarizing means is conducted to both of said first galvano scanner and said second polarizing means, and said second laser beam reflected by said first polarizing means is transmitted through said second polarizing means, and is conducted to said second galvano scanner, wherein the deflection angle by which said first galvano scanner scans is smaller than the deflection angle by which said second galvano scanner scans.
