The RIKEN Center for Advanced Photonics (RAP) is helping to realize the dream of making the invisible visible by pushing the possibilities of light to the extreme. Attosecond lasers will make it possible to see the motion of electrons, super-resolution microscopes are making the nanoworld visible, metamaterials are allowing us to manipulate the spectrum and terahertz light will open up new undreamt of technologies. The work of the RIKEN Center for Advanced Photonics focuses not simply on making discoveries that are applauded by the research community, but rather on contributing to society through practical applications.
