VAPOR PHASE GROWTH OF RUBY MONOCRYSTALS.
Abstract
The technique of preparing large, high perfection ruby monocrystals by vapor phase growth was further investigated and developed. A device was incorporated into the system which increased control of total pressure during crystal growth. Ruby crystals were successfully grown using chromium chloride and chromium carbonyl as sources of chromium vapor. Positioning the ruby crystal such that the longitudinal axis was perpendicular rather than parallel to the impinging reactant gas stream was investigated. Oxidation potential was determined to be an important process variable affecting Cr2O3 concentration. Laser oscillation of a vapor-grown ruby compared to Verneuil and Czochralski-grown rubies showed it to be of high optical perfection. (Author)
