Research Progress of Yttrium Aluminum Garnet(YAG)Transparent Laser Ceramics

Nowadays,the preparation technology of transparent ceramics is becoming more and more maturing,and partially transparent ceramics which are named the laser ceramics can be used as a laser amplifying medium.Compared with the traditional glass and single crystal laser materials,the transparent ceramic materiasl show better performance and optical properties.Currently,rare earth ions doped yttrium aluminum garnet(YAG)transparent polycrystalline ceramics are the most widely used solid laser materials.The history of transparent ceramics is reviewed.And the application domain,research status,preparation technology and facing technical problems for the YAG transparent ceramics are also introduced.
