Temperature distribution of ACCs under a 4 W-blue LD. (a) Temperature distribution and photo image of ACC1. (b) Temperature distribution and photo image of ACC2. The ceramic layer comprises 50 vol% YAG:Ce and 50 vol% glass. The Al layer is directly fused with the ceramic layer in ACC1. ACC2 has a TL between the Al and ceramic layers, and the TL comprises 50 vol% Al and 50 vol% glass. (c) Schematic diagram for the temperature distribution and heat flow (left) in the Al region of ACC1 and a magnitude image (right) of the temperature distribution in the Al region. The temperature of the glass region at the interface between the Al and ceramic region is 58.8 °C. The temperatures of the Al regions are 48.8 (HSOR) and 37.1 °C, respectively. (d) Schematic diagram of the temperature distribution and heat flow (left) in the TL region of ACC2 and a magnitude image (right) of the temperature distribution in the TL region. The temperatures of the glass and Al regions are 80.1 (hot zone) and 62.5 °C, respectively, in the TL. The temperature of the glass region adjacent to the Al is 68.5 °C.
