「CoolLaser uses the world’s highest-output 5.4 kW laser to vaporize and remove even salts, a cause of corrosion, during the removal of rust from bridges. It is attracting attention as a new preventive-maintenance technology that can also reduce environmental and worker burdens.」
Through a tour of the development and manufacturing facility by the mayor of Hamamatsu, the company reiterated CoolLaser’s existing characteristics: its high-output laser, bridge maintenance, and reduction of environmental and worker burdens. No new specific development progress or sales results were indicated. - FY2026RestatedAnnual report
「While laser output of 100 W to 1 kW is generally standard, we can achieve high output of 5.4 kW. Long-distance transmission of laser light is technically difficult, but by focusing on outdoor construction applications and advancing development, we have achieved a working range through long-distance transmission of laser light via a fiber-optic cable up to 100 m long, suitable for outdoor civil-engineering works.」
The company continues to describe 5.4 kW high output, transmission over distances of up to 100 m and circular irradiation as competitive advantages. - FY2025First statedAnnual report
