CZOCHRALSKI RUBY
Abstract
The Czochralski growth technique has been developed to yield large ruby crystals which can be fabricated into rods 2 inches diameter and 12 inches long. The optical quality of the large diameter crystals and fabricated rods has been evaluated. Ruby rods of 3/4-inch diameter and having superior optical have been fabricated from sections of the large diameter boules. Work has continued towards obtaining an improved understanding of the optical inhomogeneities in the ruby. Special emphasis has been placed on the core as this has been shown to introduce an undesirable energy distribution during lasing. Core-free rods have been fabricated from the large diameter boules and their behavior under both passive and active conditions compared to that of rods containing the core.
