Discovery of novel light sources expands
science horizon and creates new scientific research fields. New light sources
or optical technology enabling to observe what we could not see has long been
yearned for a wide variety of research fields form environment science,
biology, to atomic/molecular physics. In order to fulfill such our desire, our
group further pursues the potential of the novel optical technology being
developed at RIKEN, such as intense soft X-ray attosecond pulse sources,
near-field optical microscopes and live cell imaging. Using the advantages of
RIKEN's research complex covering physics, chemistry, engineering, biology and
medical science, applications of these light sources are also being pursued to
explore new scientific fields and to develop the industrial infrastructure.
This program is also operated through close collaboration with the Institute of
Molecular Science and a network of several universities in the Tokyo area,
contributing to the promotion of optical science and the education of young
researchers.
