Abstract
The invention relates to an improved method of making a beryllium aluminate laser rod wherein a crystal is grown by the Czochraslshi technique by core drilling and grinding. The improvement resides in heat treating the rod to release mechanical stresses induced in the single crystal rod by the griding operation to improve its optical properties. The invention also resides in a rod manufactured in this manner and to a laser employing such a rod.
