Ken-ichi Ueda

Ken-ichi Ueda (植田 憲一 Ueda Ken'ichi) is a Japanese laser scientist. He published more than 400 papers in international journals.

His research encompasses gas lasers, solid state lasers, high power fiber lasers, ceramic lasers for inertial confinement fusion research, gravitational wave detection, high field science and industrial applications.

Education

Ueda received the B.S. and M.S. degrees in electrical engineering from Osaka University in 1969 and 1971, respectively. He received a PhD in Physical Chemistry from the University of Tokyo in 1977.

Career

He was with the R&D center of JEOL from 1971 to 1976, where he investigated atomic spectroscopy and its applications. From 1976 to 1981, he was a staff member at the Physics Department of Sophia University in Tokyo, where he studied the relaxation processes of CO2 lasers. After joining the Institute for Laser Science at University of Electro-Communications in 1981 he investigated the kinetics of KrF excimers and the physics on generation of intense relativistic e-beams. He developed a high power KrF laser facility including multistaged amplifiers and a target chamber for laser-plasma interaction. He investigated ultra-high peak power lasers in the range of nanosecond to sub picosecond pulse duration. In 1990 he began to develop an ultra-stabilized laser-diode-pumped solid laser system for gravitational wave detection.

He developed super-white light generation and laser rainbow using self-trapping phenomena in gases and solids irradiated by intense and ultra-short pulses. He created new ideas on high power fiber lasers including fiber embedded disk lasers for industrial applications. He developed new concepts of solid state lasers like hybrid solid state lasers and ceramic lasers. He is a pioneer of fiber laser research in Japan. He developed kilowatt fiber-disk lasers and fiber Raman lasers and so on.

His current interests cover laser applications. He is also a pioneer of ultra-high quality optics in Japan. He was the professor and the chief of section on ultrahigh power laser section of Institute for Laser Science of University of Electro-Communications from 1981 until 2011.

He was a director of Institute of Laser Science from 1996 until his retirement.

Professional societies

He is a member of Joint Open Laboratory on Laser Crystals and Precision Measurements of the Russian Academy of Sciences. After his retirement, he is still active as a scientific advisor in Hamamatsu Photonics and also adviser for several international laser programmes and conferences.

He serves as a chairman, secretary general, and the member of the following committees; Corresponding member of Science Council of Japan Member of Committee of Journal Publication Issues of Science Council of Japan Member of IUPAP Working Group on Communication in Physics Board member of Physical Society of Japan Co-Chair of JJCQE (Japan Joint Council on Quantum Electronics) Member of ICQE (International Council on Quantum Electronics) Program Co-chair of CLEO PR 2009 Editor-in-chief of Optical Review Associate Editor of Laser Physics Letters Editor of High Power Laser Science and Engineering.

He served on many academic committees. Board member: OSA (2000-2002), JSAP (1999-2001), IPAP (2000-2001), Laser Society of Japan (2006-) Chair: IUAPA 017 (2005-2008), CLEO PR STC (1995-2007) Conference Chair: IQEC 2005 in Tokyo, Kaya conference in 2004 Editor: Topical Editor of Applied Optics (1996-2002), JOSA Editor for topical issue (2007), Quantum Electronics (2000-2003.

Recognition

Ueda is an OSA fellow, JSAP fellow, and got many science awards including National Medal with Purple Ribbon from Japanese government which is one of the best recognition by Japanese Government towards the contribution of Science.
