YAG/Nd:LuAG composite laser materials prepared by the ceramization of YAG single crystals

Composite YAG/Nd:LuAG laser materials were prepared by the ceramization of YAG single crystals from the original bonding interfaces of green bodies (optical contacted YAG crystals and Nd:LuAG ceramics). And the morphology, microstructural characteristics and optical properties of the composite materials were studied. The results indicated that Nd:LuAG ceramics and YAG crystals were completely combined without bonding interfaces. They were pore-free at the original contacting interfaces of the YAG/Nd:LuAG transparent materials and the in-line transmittance of the specimens reached 84% at 1064 nm. This suggests that ceramization of YAG single crystals is a promising way to fabricate composite YAG/Nd:LuAG transparent materials.
