Our team investigates new optical technologies for solving world-wide environmental and energy problems. We are mainly developing remote-sensing system of poisonous gas, lidar as an atmospheric monitor for high energy cosmic ray observation, and solar-pumped laser for advanced energy source. We are also developing tunable laser-based biosensors for biomedical and agricultural applications. These researches will contribute to build and to maintain social environment that humans can live safely. Moreover, we are investigating fundamental research topics including particle control with high power Lyman α coherent source, and development of laser pumped neutron source. New applied researches were performed on the basis of basic research of laser materials, and nonlinear optics.
