ABSTRACT:
A laser apparatus and method for producing a deckle edge on laser cut paper, the apparatus including a laser source projecting a laser beam intercepted by an optical device for providing a line focus of the beam on the paper, with the line focused beam having an energy gradient on the paper adjacent the intended edge, the movement of the paper relative to the beam, in conjunction with the inhomogeneous nature of the paper providing a deckle edge having differing degrees of etch adjacent the cut edge. The optical device is a spherical mirror set off-axis relative to the primary laser beam.
