Abstract
An alignment apparatus for aligning a main, high power laser beam with a workpiece by the use of a low power laser beam while the main, high power laser beam is shuttered off from contact with the workpiece includes a periscope for displacing the low power beam laterally to be coaxial with the axis of the first beam during the time that the high power beam is shuttered off from the workpiece. The alignment apparatus includes adjustment mechanism for adjusting the angular position of the low power laser to make the axis of the low power laser beam exactly parallel to the axis of the high power laser beam for the particular periscope being used.
