Yb∶Y_3Al_5O_(12)/Y_3Al_5O_(12)复合晶体的制作和光谱性能

采用热键合技术,制作中运用不同的工艺参量制作出12片Yb∶Y3Al5O12/Y3Al5O12(Yb∶YAG/YAG)复合晶体。利用偏光显微镜对其键合界面进行了观察,研究了样品的透射光谱,从而确定出复合晶体合适的制作工艺。通过透射光谱的形状和透射率来表征复合晶体键合界面的质量。研究表明Yb∶YAG/YAG复合晶体键合质量较好,可实现一体化。

The composite Yb:Y<inf>3</inf>Al<inf>5</inf>O<inf>12</inf>/ Y<inf>3</inf>Al<inf>5</inf>O<inf>12</inf> crystal was made by thermal bonding method-twelve pieces of composite crystals were made by different technological parameter in manufacturing process. The bonding interface of the composite crystals were observed by optical microscope, transmission spectra of the composite crystals were studied. We get appropriate making technology of the composite crystals from above result. Bonding quality of composite crystals were characterized by the shape of transmission spectra and transmittance of Yb:YAG/YAG composite crystals. All experiments show that the composite Yb:YAG/YAG crystal has good bonding quality and integration is feasible.
