Laser ablation is the use of lasers to instantly vaporize materials. This technology may seem like something out of a science fiction movie, but in reality it is deeply rooted in our lives and industry. It is used in medical fields to restore vision, in laser processing in automotive manufacturing, and even in the latest technology in semiconductor manufacturing.
Furthermore, by increasing the intensity of the laser, plasma can be created from laser ablation. This "Laser Ablation Drift Plasma" (LADP) is a very dense, high-temperature plasma with the characteristic of collective motion in a certain direction. The application of this property opens up new possibilities for ion implantation and deposition technologies.
- Fusion of Green Transformation and Plasma Technology
The world is currently undergoing a 'green transformation' (GX), which refers to the transformation of industries and technologies toward a sustainable society while reducing environmental impact. Improving energy efficiency and optimizing resources are core GX issues. We believe that this new surface modification technology using laser ablation plasma (LADP) can contribute to the realization of GX.
Specifically, LADP is being applied to Plasma-Based Ion Implantation and Deposition (PBIID) technology to dramatically improve the accuracy and efficiency of surface treatment. This technology not only increases the wear resistance of molds and machine parts, but also extends the life of parts and reduces disposal due to wear and deterioration. This reduces energy consumption and resource use throughout the manufacturing process and contributes to building a sustainable production system for GX.
- Next-generation manufacturing technology with high efficiency and low energy consumption
By applying LADP, plasma ion implantation techniques can be performed more efficiently at lower energy than conventional methods. For example, selective and localized ion implantation and deposition can be performed on parts with complex geometries, reducing wasted energy and materials. This innovation leads to the production of longer-lasting products by preventing wear and deterioration of mechanical parts, resulting in resource and energy savings.
Furthermore, advances in surface treatment technology are expected to improve the energy efficiency of the entire manufacturing process, reducing waste and extending product life. This will enhance the sustainability of the manufacturing process while at the same time reducing the impact on the global environment, helping to make the GX a reality.
Our laboratory hopes to contribute to a sustainable society of the future by developing such energy-saving and environmentally friendly technologies. Together with our students, we will pursue the possibilities of new technologies on a daily basis with free thinking and pave the way toward GX.
