Green Photonics for laser-based manufacturing

— Photonics contributes to a sustainable society in the “photon century” —

Abstract

Green Photonics is expected to reduce energy consumption and pollution associated with a broad range of manufacturing processes. The paper is a study on the development of laser-based methods and their applications. High precision surface processing of various materials is a key technology for practical industrial applications. Well-defined micro-fabrication with high-speed and high-quality treatment of materials was performed by laser irradiation. The technical challenges are particularly great in this area, but recent developments in laser processing have opened up new frontiers. Due to advances in laser processing systems, and greater understanding of the phenomenon of diverse excited states generated by laser irradiation, these methods can be considered mature and versatile techniques that present some key benefits over other more established fabrication techniques.
