Abstract

A φ220 × 200 mm sapphire crystal, with <1010> oriented had been grown by sapphire growth technique with micro-pulling and shoulder at cooled center (SAPMAC) method. In the research, the temperature gradient of the crystallization region was 0.5-1.0°C/mm and the growth velocity was 0.1-2 mm/h in vacuum environment. The result shows the transmission of the sapphire slice with 1 mm thickness is at least 85% in the range from 2500 to 4000 cm^-1.
