All ceramic composite with layer by layer structure by advanced ceramic technology

Since the composite laser media using single crystal such as Nd:YAG and undoped YAG was reported in 1998[1], the composite with various structures provided to experimental or industrial field. However, conventional bonding condition is not enough for laser application, and fabrication process is extremely complex and long delivery owing to necessity of polishing and diffusion bonding. Ceramic composite laser gain media having layer by layer and clad-core structure were fabricated successfully for the first time by advanced ceramic processing. Advanced ceramic technology provides a direct formation of composite having complex structure without polishing and diffusion bonding. The bonding condition of ceramic composite was confirmed to almost optically perfect, so we could oscillate successfully using composite laser media.
