Outline
The discovery of novel light sources expands the horizons of science and creates new scientific research fields. Unexplored wavelength regions of the light spectrum (extreme wavelengths) have long been seen as areas of new potential for the promotion of scientific and industrial development. We pursue the potential of novel light sources now under development at RIKEN, such as intense soft-X-ray attosecond pulses, near-field photons and terahertz light waves. Those extreme light infrastructures play key roles in creating the new optical science fields of atto-photonics, nano-photonics and tera-photonics, which make up extreme photonics. Our efforts to explore new scientific fields through these light sources and applying them in the fields of physics, chemistry, engineering, biology and medicine are enhanced by the advantages of using equipment provided by the RIKEN research complex.

In our group we further pursue 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.

Because of the difficulty heretofore experienced in detecting, not to mention generating, terahertz light, it has been considered by many in scientific and industrial research to be the last frontier in the study of electromagnetic waves and remained largely unexplored.
