Dr. Kyung-Han (Kyle) Hong is a Principal Investigator of MIT Research Laboratory of Electronics (Optics and Quantum Electronics group) and a Member of Technical Staff at MIT Lincoln Laboratory. Dr. Hong was educated at the Korea Advanced Institute of Science and Technology (KAIST), where he completed his B.A. (1996), his M.S. (1998) and Ph.D. (2003) degrees, all in Physics. After his Ph.D., in 2003 and 2004, he did postdoctoral work at the University of Michigan under Prof. Gérard Mourou, the pioneer of chirped-pulse amplification (CPA) technique and 2018 Nobel laureate in physics. Dr. Hong returned to Korea and had been a Senior Research Scientist at the Advanced Photonics Research Institute (APRI), Gwangju Institute of Science and Technology (GIST) when he joined MIT as a Research Scientist with Franz Kaertner’s group in 2007. He was promoted to a Principal Research Scientist at MIT RLE in 2012 and joined Lincoln Laboratory in 2018. He also participated in Compact X‑ray Light Sources project at Arizona State University from 2015 to 2018.

Dr. Hong’s accomplishments span a range of topics in ultrafast laser sciences. His research has focused primarily on the ultrashort pulse amplification and its application to high-field physics such as attosecond physics and relativistic optics. At MIT he has demonstrated high-flux high-harmonic generation (HHG)-based table-top soft-X-ray sources, novel few-cycle and single-cycle mid-infrared laser sources, and THz-driven electron acceleration. Before joining MIT, he developed TW- and PW-class Ti:sapphire CPA lasers and high-repetition-rate Ti:sapphire amplifiers and also demonstrated GeV laser-wakefield electron acceleration.

He has authored and coauthored more than 100 peer-reviewed SCI journal papers, more than 170 international conference papers, and 6 patents in the U.S., Korea, and Japan. He is a topical editor of High-Power Laser Science and Engineering and a regular reviewer of scientific journals, such as Optics Letters, Optics Express, and Nature Communications, as well as government-funded grant proposals. Dr. Hong is a member of the Optical Society of America and American Physical Society.
