Principal Scientist
Dr. Hiroyuki FURUKAWA (Ph.D. in Engineering)
Dr. Hiroyuki Furukawa graduated from the Department of Physics, Faculty of Science at Kyushu University.
He completed his doctoral program in the Department of Electromagnetic Energy Engineering at the Graduate School of Engineering, Osaka University, receiving a Ph.D. in Engineering in 1991.
After serving as a Research Fellow of the Japan Society for the Promotion of Science (JSPS), he joined the Institute for Laser Technology (ILT) in 1992, where he conducted research for many years in laser physics, plasma physics, and laser-based technologies.
His research has focused on topics such as:
- Thermal stress and birefringence analysis in solid-state lasers
- Laser ablation processes
- Laser decontamination technologies
- Interactions between lasers and high-temperature, high-density plasmas
He has published numerous research results in the fields of laser applications and numerical simulation, contributing significantly to both experimental and computational studies.
After retiring from the Institute for Laser Technology in 2023, he joined Glencal Technology Co., Ltd. as Principal Scientist, where he contributes to the company’s technology research and development by applying his expertise in laser and plasma physics.
