The objective of this project is the `Development of Laser Technology` for the use of nuclear facilities. For the last first year, a 1kW-class Nd:YAG laser materials processing system has been assembled and laser sleeve welding related materials have been analyzed. Furthermore, laser metrology for the fast and accurate inspection of defects in steam generator U-tube has been also constructed and 5W high-resolution tunable dye laser, which is pumped by CVL, has been developed for applying to atomic spectroscopy technique development. A millimeter-wave free electron laser (FEL) system using an electrostatic accelerator has been designed and A one-dimensional simulation code has been developed to expect the gain of FEL. (Author).
