| Abstract: | MgTa2O6 single crystals, which adopt trirutile structure, were successfully grown by a floating zone method, and their optical properties were invetigated. The as-grown crystals were black and opaque, but subsequent annealing in air from 1200° to 800°C rendered the crystals pale-yellow and transparent. The refractive indices for ordinary and extraordinary rays were 2.07 and 2.18 under white light, respectively, and the birefringence was 0.11. The interference figure observed with a polarizing microscope was typical one for an optically uniaxial crystal, which indicates that the crystal was optically uniform. Transmittance in the wavelength range of 500 to 2000nm was about 75%, which approximately corresponded to the theoretical value calculated from the refractive index. The absorption edge of MgTa2O6 was at 290nm. |
