Outline of Final Research Achievements

To realize the high performance Faraday isolator for high power laser, basic research of YIG (Y 3 Fe 5 O 12, yttrium iron garnet) ceramics material for high power laser which can produce 3 dimensional magnetic photonic crystal structure was performed. The translucency of YIG ceramics was confirmed as the first time. Furthermore, we measured the magneto-optic property that is the comparable of the YIG single crystal. We plan to improve the optical characteristics and realize the magnetic photonic structure using this material by studying material process etc in the future.
