| Zusammenfassung: | A laser material processing system and method focus a laser beam to a smaller spot size with a high power density using a movable beam expander to provide high resolution laser beam for engraving and/or cutting. A movable beam focusing assembly containing a beam expanding optics and a beam focusing optics is a part of a motion system providing a high power density focused beam within the material processing area minimizing size and weight of the laser beam positioning optics and avoiding the problems inherent in handling and positioning a larger diameter beam. |
