Abstract

A method and an apparatus pertaining to polarization combining in additive manufacturing may involve emitting two or more beams of light with a first intensity. Each of the two or more beams of light may be polarized and may have a majority polarization state and a minority polarization state. A respective polarization pattern may be applied on the majority polarization state of each of the two or more beams of light. The two or more beams of light may be combined to provide a single beam of light.
