Aluminum Oxide Chromium doped Crystal Description

Aluminum Oxide Chromium doped Crystal, commonly known as ruby, is a crystalline material used in various applications. The chromium ions replace some of the aluminum ions in the crystal lattice, giving the crystal a red color and unique optical properties. Rubies are used in lasers, specifically solid-state lasers, where they serve as the lasing medium. They are also used in high-precision mechanical parts, watches, and jewelry due to their hardness and aesthetic appeal.
