IN PRODUCING RUBY FOR OPTICAL MASER APPLICATION, THERE ARE SEVEAL GROWTH VARIABLES WHICH AFFECT CRYSTAL QUALITY. The growth information on two of ten lots of ruby crystals grown under different growth parameters is presented. These lots of ruby crystals were grown with thermal gradients vertically down the crystal of 300 and 150 C, other growth conditions remining constant. Preiminary examination indcates the crystals grown with the lower thermal gradient to have superior crystal quality. Author
