Laser beam has several features such as same wave-length, same-phase and beam traveling linearity. The beam, because of these reasons, is focused on a small area, and high-power density is easily obtained by optical devises. Non-contact, high-speed and precisely controlled laser irradiation are significant advantages as well, and therefore, laser technologies have been widely used in many industries.

By taking account of these strengths, JAEA has developed laser cutting and laser decontamination technologies for nuclear power plants decommissioning. JAEA has also applied our laser technologies for industrial use, including laser quenching, laser rust-resistance and laser penetration plastic-resin joining.

These R&Ds activates are explained below, and a click of titles links to each content.
