서울시립대 이주한 교수, CLEO-PR 2026 국제학술대회 기조강연

Professor Jung-hwan Lee of Seoul National University delivered a keynote speech at the 17th Pacific Rim Conference on Lasers and Electro-Optics (CLEO-PR 2026) held in Beijing, China from August 2nd to 6th. This conference, sponsored by organizations such as Optica, IEEE Photonics Society, IEICE Electronics Society, IEICE Communications Society, JSAP, OSK, COS, ANZOS, and TPS, is considered Asia's largest event in the field of lasers and optical technologies. Over 1,000 researchers from around the world participated.

In his presentation, Professor Lee focused on 'Development of High Power Fiber Laser Components in South Korea'. Specifically, he showcased research conducted at Seoul National University's Laser and Optoelectronic Materials Research Laboratory, in collaboration with startup company Kromagnet. The core technology involves creating laser cladding devices through chemical etching based on a non-equilibrium chemical etching system.

This technique ensures uniform temperature distribution along the device length by gradually reducing the depth and period of the etching section, while also precisely controlling the size of the etching and non-etching regions. Professor Lee emphasized that this technology has been patented in both South Korea and the United States, and achieved superior performance compared to products of leading companies in Germany and the United States.

He expressed that this keynote speech aimed to demonstrate the excellence of Seoul National University's research team to the global community. Professor Lee continues to work with Kromagnet to further advance the technology and is pursuing partnerships with Japanese, French, and Malaysian companies to expand the international export of related products.

Notably, Professor Lee serves as Deputy Chair of the Korea Optical Society (OSK) and is a Fellow of the Optical Society of America (Optica).
