R&D of spatial light control technology

R&D of spatial light control technology for performing high-quality and high-throughput laser processing

Implementation period: FY 2018 - FY 2022

While conventional laser processing can perform precise, high-quality processing, it has the bottleneck of low processing throughput. Processing speed can be increased by parallelizing laser beams. Therefore, a device that can control high-power lasers was required. In this project, we tried to develop a spatial light control device that can control the two-dimensional phase distribution of light with high precision and implement the device into material processing with high accuracy and throughput. Furthermore, by implementing digital feedback technology, we aimed to realize a fundamental technology that achieves high precision and stability in manufacturing.
