Outline

Text (EN) Our team leverages aSdvanced photonic technologies to tackle global challenges such as agriculture, aging societies, energy resource management, and environmental change, while also contributing to breakthroughs in fundamental science. We develop optical remote sensing systems for detecting gases in daily life and industry, atmospheric monitoring tools for analyzing cosmic ray and solar activity indicators, breath analysis techniques for health diagnostics, short-range LiDAR for tunnel degradation detection, and hydrogen-based renewable energy systems. In fundamental science, we are advancing high-power coherent Lyman-alpha light sources for ultra-slow muon generation in particle physics, as well as laser-based solutions for space debris removal and spaceborne sensing. These efforts are rooted in core research on photonic materials and optical control. We focus especially on tunable infrared light sources based on nonlinear wavelength conversion for quantum sensing.
