Laser Processing Lab
Machine-translated · View original
A lab exploring laser-based joining and processing of materials from the fundamentals.
AboutAbout the lab
Aiming to integrate laser science and production engineering.
The Laser Processing Lab studies, from the fundamentals, processing methods that use lasers to join and cut materials, modify surfaces, and separate or remove material.
It works to clarify what happens during processes such as welding and cutting, and based on the results aims to build mechanisms for controlling and optimizing processing.
It also evaluates the applicability of joining dissimilar materials and of metal 3D printing technology, and develops welding and joining processes suited to materials with new functions.
The lab also works on surface modification, which gives materials the surface functions essential for practical use, and is advancing the controlled application of lasers and particle beams to thick-film processes such as cladding and aerosol deposition.
Key terms
- Laser cladding
- A processing technology that uses a laser to form a coating on the surface of a material. This lab works on producing high-quality coatings.
- Femtosecond
- A unit of time equal to one quadrillionth of a second. This lab mainly uses lasers with 150-femtosecond pulses.
- Ultrafine particle beam
- A method in which ultrafine particles are accelerated by a carrier gas and made to hit a substrate at high speed. It can form films at room temperature.

ResearchResearch themes
The lab develops processes using various beams, including semiconductor lasers, femtosecond lasers, nanosecond lasers, and ultrafine particle beams. Its research page introduces technologies for metal additive manufacturing, femtosecond laser processing, ultrafine particle beams, and semiconductor laser processing.
*Illustrative imageLaser-Based Metal Additive Manufacturing
The lab develops metal additive technologies, including high-quality coating formation by laser cladding and 3D printing of copper using blue semiconductor lasers. By increasing the power of blue semiconductor lasers and developing beam superposition technology, it has made copper processing possible.
*Illustrative imageFemtosecond Laser Processing
The lab mainly processes materials with lasers of 150-femtosecond pulse width. In the areas of a titanium substrate irradiated with this laser, periodic structures form.
*Illustrative imageRoom-Temperature Film Deposition with Ultrafine Particle Beams
Ultrafine particles are accelerated by a carrier gas and made to hit a substrate at high speed, which has made film deposition at room temperature possible. The lab forms films of lead zirconate titanate used in piezoelectric elements, bioactive hydroxyapatite, and photocatalytic titanium oxide.
*Illustrative imageSemiconductor Laser Processing
Semiconductor lasers have higher oscillation efficiency than YAG lasers and carbon dioxide lasers, and enable precise processing when heat input conditions are properly controlled. The lab has welded materials thinner than a human hair, bent 5 mm thick plates, and welded aluminum alloys.
