About

Toshifumi Matsumoto is a pioneering figure in high-power laser materials processing, with a career distinguished by his work on the world’s most powerful CO2 laser systems. His key research areas include laser welding, cutting, and surface treatment, with a particular focus on developing industrial-scale, three-dimensional processing capabilities. Matsumoto’s major contribution is the integration of a 50kW-class CO2 laser oscillator with a portal processing device and an internal path type CO2 laser robot—a groundbreaking achievement that enabled unprecedented material processing power and precision. This work, detailed in his 1996 paper, has garnered 3 citations, reflecting its foundational role in advancing laser manufacturing technology. While his citation count is modest, the impact of his engineering feat is immense, as it pushed the boundaries of what was possible in industrial laser applications. Matsumoto’s legacy lies in demonstrating that ultra-high-power lasers could be effectively harnessed for complex, three-dimensional tasks, paving the way for modern laser-based manufacturing in aerospace and automotive industries.
