The arbitrary dynamic control of both amplitude and polarization distributions is attracting strong interest in laser processing field to manage the quality and to collect valuable polarization characteristics of processing materials in smart manufacturing. We present a holographic method to generate arbitrary polarization state of multiple beams by synchronizing two phase-only liquid crystal spatial light modulators (SLMs) with imaging feedback system for hologram designing of each polarization state. This research work will help to accelerate the use of liquid crystal SLMs for high-throughput and optimized additive manufacturing.
