RESEARCH ON COHERENT ELECTROMAGNETIC RADIATION MATERIALS.
KORAD CORP SANTA MONICA CALIF
Improvement of laser materials with respect to high output energy and power. Emphasis has been on the growth and evaluation of ruby. Results of detailed studies of the Verneuil flame fusion method of crystal growth and, in particular, the technology of the starting powder are presented. Several methods which have been developed for evaluation of rubies, including laser testing, are described. The solutions to several problems relating to crystal quality are given. A substantial improvement in the size and quality of ruby laser crystals was affected during the contract period. Data obtained on other potential laser materials is included. Author
