Surface modification: Enhanced functionality through water-repellent processing using ultrashort pulse lasers.
By using ultra-short pulse lasers for precision machining, fine structures (micro and nano) are created on metal surfaces to impart a water-repellent effect and modify the surface. Water and oil repellency leads to improved functionality, such as preventing product seizure and rust. The technology for adding fine structures to metal surfaces can also be applied to components that require reduced friction and improved sliding properties.

Company information
At "HIKARI LASER LAB.", we offer services for precision processing using ultra-short pulse lasers, including "contract processing," "development agency," and "marking." Precision processing and surface modification/internal marking using picosecond and femtosecond lasers are utilized in various industrial equipment across sectors such as the medical industry, automotive industry, and semiconductor industry. Recently, there has been a demand for surface modification not only for shape processing like fine hole drilling, cutting, trimming, and groove processing but also for enhancing functionalities such as water repellency, release properties, friction reduction, and improved sliding properties. Additionally, there is a demand for marking inside glass from the medical industry. Laser processing is possible on a wide range of materials, including transparent materials like glass and diamonds, difficult-to-cut materials like titanium, and resins, CFRP, ceramics, and polyimides. Regarding surface modification, we have received requests to improve the release properties of molds. We will continue to "challenge" ourselves in precision processing and surface modification using ultra-short pulse lasers to meet our customers' needs!
