<p>In a laser machining apparatus for machining a workpiece ( 13 ), a laser ( 2 ) emitted from an oscillator ( 1 ) is dispersed into a first laser beam ( 7 ) that is passed through a first polarizing means ( 6 ) and is reflected, via a mirror ( 5 ), by a second polarizing means ( 9 ), and a second laser beam ( 8 ) that is reflected by the first polarizing means ( 6 ), is scanned bi-axially by a first galvano-scanner ( 11 ), and is passed through the second polarizing means ( 9 ); scanning by a second galvano-scanner ( 12 ) is carried out, and a third polarizing means ( 15 ) for polarizing angle adjustment, capable of angle adjustment, is disposed before the first polarizing means ( 6 ).</p> |
