We have chosen attractive laser technologies for the atomic nuclear energy researches and industrial applications originally developed at Kansai and Tokai Institutes to start our own activities at Atom Plaza. In 2012, we plan to move to the new institute building which we tentatively call “Joint research and development center for plant engineering” located in the downtown Tsuruga to do extensive activities of our Institute.

In order to apply the laser techniques into the traditional cutlery technology such as heating, cutting, molding, forging, burnishment and printing processes, we are developing the relevant techniques in collaboration with Echizen

Uchihamono Association. We hope to extend the area of laser applications.

Principle of Laser PeeningWhen an intense laser is focused down to a material, the laser driven ablation occurs and high

pressure region appears on the surface of the material, where the high pressure shock wave is driven by the pressurized region. Then the shock wave makes modification of mechanical properties of the material during and after the shock wave propagates. Finally, the residual stress mains in the material.
