Research Abstract

Novel magneto-optical single crystal, Tb3(Sc1-xLux)2Al3O12 (TSLAG), has been designed and large size TSLAG single crystal was developed for high-power laser machinery. TSLAG showed a higher visible transparency and a larger Faraday rotation than conventional material, Tb3Ga5O12. TSLAG is therefore very promising material in particular for new magneto-optical isolator applications in the VIS-NIR wavelength.
