If the inner light scatter is eliminated, cera- mics can become transparent or optical ceramics [1,2]. With great potentials in optical windows, sensors and lasers, optical ceramics have received great attentions since 1950s [1]. As the gain medium of solid-state lasers, optical ceramics can combine the advantages of large size, high transparency, high mechanical and thermal stabi- lities, and ease for dispersing the luminous atoms and groups [3]. For comparison, single-crystal gain mediums can suffer high power density but are difficult to grow into large size, while glasses and polymers have reversed characteristics.展开更多
