Transparent optical ceramics

Advantages of transparent ceramicsHigh rare-earth ion concentrationMass production High power and efficiency lasersFlexibility of designed structuresExcellent mechanical propertiesSesqui-oxide laser ceramicsLarge-size fabricationDevelopment of new laser materials

Page 3: Transparent Ceramics

Studies of Grain-boundary microstructure and chemistry would provide a fundamental understanding of the roles of grain-boundaries in optical transparency. In turn, this would enable control over the influence of nanometer to subnanometer microstructural changes and chemical composition for the development of high-performance ceramic lasers
