Composite YAG /Nd:Lu AG transparent ceramics were fabricated by a thermal bonding process. The spatial distribution of ions around the original bonding interface of the YAG /Nd:Lu AG composite laser ceramic was investigated. Around the original bonding interface, Lu 3+ and Y 3+ ions were replaced with each other in dodecahedral symmetry sites. Results from X‐ray photoelectron spectroscopy ( XPS ) and energy dispersive spectroscopy ( EDS ) quantitative chemical analyses positively show that the distance of Y 3+ ions diffused in the Lu AG part is about 35 μm, while Lu 3+ ions’ diffused distance in the YAG part is about 5 μm. This corresponds to the diffusion coefficient of Y 3+ ions and Lu 3+ ions ( D Y =2.43 ×10 −10 cm 2 /s and D L u =0.56×10 −10 cm 2 /s at 1750°C). The formation of Y x Lu (3− x ) Al 5 O 12 polycrystal in the bonding section explains the complete combination of Lu AG and YAG without a bonding interface. Moreover, no diffusion phenomenon of Nd 3+ ions was detected near the original bonding interface.
