ABSTRACT:
A constant length laser device for use with laser generating means comprising a first moveable optical reflector carriage for deflecting a laser beam 180.degree. onto a spaced apart second moveable optical carriage which further deflects the laser beam 90.degree. onto a workpiece, such as a printing roll, to be laser treated and wherein the first and second carriages are synchronized to move in the same direction with the first carriage moving at a speed one half that of the second carriage so as to produce a constant length laser beam.
