Abstract
A laser marker system for marking indicia onto a substrate includes an exit lens having a focal length and a single laser source. The surface of the substrate to be marked is positioned generally at the focal plane of the lens. The single laser source is arranged so that its energy output beams are oriented in a generally parallel relationship. The single laser source includes segmented reflecting means for generating a plurality of output energy beams to create a column of spots on the substrate with a higher resolution. The segmented reflecting means is comprised of a back-reflecting mirror which is formed of a plurality of different mirror segments. A device is provided for moving each of the plurality of different mirror segments between a lasing position and a non-lasing position to vary the number of output energy beams and thus the number of spots on the substrate.
