研究の背景 Background


The interaction between light and matter may have a wide variety of undiscovered phenomena and effects. On the other hand, recent progress in photonics is quite rapid and a lot of technologies such as power enhancement, expansion of wavelength region and innovation of short pulse generation have been successively achieved. These novel technologies in photonics would pave a road to new research field in material science.

研究の目標 Outcome


Our goal is to find unknown light-matter interaction. To that end, we develop new light source and investigate its novel characteristics. At the same time, we perform the development of novel material synthesis process and the synthesis of new materials by using state-of-the-art photonic technologies. As a synergetic effect of these results, we strive to explore a new research field regarding light and material.
