About
Tomonao Hosokai is a leading researcher in the field of laser materials processing, with a primary focus on laser peening technology for enhancing the mechanical properties of structural alloys. His work centers on the development of compact, portable laser peening devices—a significant departure from traditional, bulky systems—and their application to improve fatigue life and introduce beneficial compressive residual stresses in metals. Hosokai’s major contributions include demonstrating that a thumb-sized Nd:YAG microchip laser, delivering pulse energies as low as 1.7 mJ, can effectively improve the residual stress state and fatigue properties of high-strength materials such as HT780 steel butt-welded joints and A7075 aluminum alloy. His most-cited paper (2022, 20 citations) details the development of this portable device, while a related study (2021, 14 citations) confirms its efficacy on aluminum alloys without the need for a protective coating. This miniaturization work is notable for making laser peening accessible for on-site and collaborative robotic applications, potentially transforming maintenance and repair in aerospace and automotive industries.
