Abstract
A laser gain medium and a method of manufacturing a laser medium, such as a laser rod, or slab for use in high-powered laser peening systems. A laser medium and method reduces stress risers along the surface of the amplifier medium by grit blasting, polishing, etching, annealing, and by eliminating platinum inclusions within the laser glass.
