Outline of Department
In Department of Quantum Applied Photonics, research and development (R & D) that contribute to the development of quantum technologies (material and life science), medical technology, and safety and security technologies are conducted. Using the advanced technology of ultrashort pulse lasers based on high-power lasers, we develop methods for wavelength conversion to various wavelength ranges from soft X-rays to terahertz and ion acceleration driven by lasers and handle a wide range of subjects from basic science related to atoms, molecules and optics (AMO), material properties in liquid and solid phases. We also perform theoretical research and numerical simulations.
In cooperation with Takasaki Institute for Advanced Quantum Science, which is superior in development and use of quantum materials, we play a role in "Foundational Quantum Technology Hub", one of Japan's Quantum Technology Innovation Hubs (QIH). We will elucidate and create new quantum functions that utilize the ultrafast property and controllability of lasers. Using ultrafast measurement technique, we will clarify the details from the viewpoint of quantum coherence.
We conduct R & D of laser-driven ion accelerators with the aim of significantly reducing the size of accelerators used in heavy ion cancer treatment and aim to realize next-generation heavy ion cancer therapy devices (quantum scalpels). In addition, we develop medical diagnostic equipment using lasers, and we are also investigating the mechanism of DNA damage that could not be investigated by conventional radiation by taking advantage of the local characteristics of laser filaments and laser-driven heavy ion beams, both in terms of time and space, for DNA radiation damage, which has been studied for many years at QST.
We develop remote-sensing technology using high-intensity lasers as an inspection technology for many social infrastructures that have been built for more than 50 years after the period of high economic growth, especially tunnels and bridges. It has attracted attention as a remote and digitized inspection method, and in collaboration with Photon Lab Co. Ltd., a certified venture company of QST, we are promoting sophistication for social implementation and conducting demonstration tests of laser hammering inspection at infrastructure facilities throughout Japan.
The four projects are currently ongoing in our research department, and we emphasize flexible cooperations between projects on an ad hoc basis, as well as collaboration with other groups inside and outside QST. We would like to make effective use of our laser technology and measurement and numerical simulation technologies, so if you are interested, please do not hesitate to contact us.
