摘要：

A hundred-watt level blue collimated laser is used to excite YAG: Ce phosphor ceramics to prepare a high-power white laser-based illuminant. A composite ceramic cooling device is prepared to reduce the operating temperature of YAG: Ce phosphor ceramics by using nano-silver to weld ceramics onto a copper block with a watercooling device. Phosphor ceramics encapsulated with the above device can withstand the excitation of a 123 W blue laser, and its output luminous flux value reaches 14600 lm. The stable output time of the laser-based illuminant is over 30 min, and the operating temperature of the phosphor ceramic surface is only 270 degrees C. Compared with the non-cooling device package, the luminous flux of the laser-based illuminant composed of phosphor ceramics packaged with the above structure is increased by 252.8 %. The experimental results show that the composite ceramic cooling device can effectively reduce the operating temperature of phosphor ceramics which is an effective way to realize white laser-based illuminants over 10000 lm.
