About

Takunori Taira is a pioneering force in the development of compact, high-power laser systems and their industrial applications. His research centers on microchip laser technology, laser peening, and advanced thermal management for solid-state lasers. Taira’s major contribution is the invention of the “distributed face cooling” (DFC) chip, which enables tiny integrated lasers to achieve over 30 MW peak power—a breakthrough validated by finite element analysis and cited 33 times. This work paves the way for laser-armed robotics and ubiquitous high-peak-power sources. In parallel, Taira has revolutionized laser peening (LP) by miniaturizing the device to a thumb-sized Nd:YAG microchip laser, making portable LP feasible for improving fatigue properties of metals like HT780 butt-welded joints (20 citations) and A7075 aluminum alloy (14 citations). His palmtop-sized LP system introduces compressive residual stress without coating, enhancing durability in aerospace and automotive components. With over 67 citations across these key papers, Taira’s work bridges fundamental laser physics and practical engineering, offering students and researchers a compelling model of how compact, efficient lasers can transform materials processing and industrial maintenance.
