Abstract: Additive manufacturing systems, area scanning laser systems, and methods for performing an additive manufacturing process are provided. An exemplary additive manufacturing system includes a laser generation device for producing a laser beam. Further, the additive manufacturing system includes an optic element for forming a first portion of the laser beam with a first polarization and a second portion of the laser beam with a second polarization different from the first polarization to encode an image in the laser beam. Also, the additive manufacturing system includes a selective beam separator configured to direct the first portion of the laser beam onto a material to be sintered or melted. The additive manufacturing system includes a recycling system for receiving the second portion of the laser beam.
