KAIST, the birthplace of Korean optics community, has been the center of optical researches in Korea. The optics group of KAIST conducts full-scale researches on the theme of light-matter interactions. Its research activities cover a wide range of topics in optics; quantum optics and quantum electronics, laser spectroscopy, classical optics, fiber optics, semiconductor lasers, and high power lasers. Many of these researches are often carried out in the form of dynamic collaboration among academia, national laboratories and industry, by researchers from, different backgrounds working closely together.
Recent progresses include the studies of light-matter interactions with intense laser fields, optical fiber sensors, fiber lasers and amplifiers, nonlinear effects in the optical fiber, optical band-gap material, ultra-highpower/ ultra-short-pulse lasers, plasma spectroscopy, X-ray lasers, vertical cavity surface emitting microlasers, semiconductor nonlinear optical phenomena, high-resolution spectroscopy, and nonlinear effects with squeezed light.
