CZOCHRALSKI RUBY.
Abstract
Overall objective of this program is to develop the Czochralski technique for the growth of large rubies of high optical quality, for laser use. Process has been scaled up to crystals 5/8 in. in diameter and 8 in. long, of similarly high quality as the smaller crystals growth previously. During high power active laser tests, internal crystal damage was observed. The damage was shown to originate at particulate scattering centers of the crucible material present in the crystal. By careful control of atmosphere above the melt, the scattering centers can be eliminated. (Author)
