为了提高烟火固体激光器泵浦源 Zr/KClO4的泵浦效率，在烟火剂 Zr/KClO4中引入具有催化性能、高比表面积、强吸附能力、高强度的碳纳米管（CNTs），借助差热分析技术和光电探测技术研究了碳纳米管对泵浦源用烟火剂 Zr/KClO4（60/40）的热分解和光辐射性能的影响。结果表明：CNTs的加入对 Zr/KClO4的热分解特性和光辐射能均有显著的影响。随着 CNTs 添加量的增加，烟火剂的燃烧速率和放热量均逐渐增加，药剂的融化吸热峰减弱，甚至趋于消失，药剂的光辐射能量却呈现出先增加后降低的趋势。当 CNTs含量为体系总质量的0．50％时，药剂总光辐射能达到了1830 J·g-1，其中分布在钕（Nd）：钇铝石榴石（YAG）激光增益介质的三个强吸收带（590±10）nm，（750±10）nm和（808±10）nm内的有效光辐射能分别提高了41％，25％和31％。

To improve the pump efficiency of Zr/KClO4 pyrotechnic reagent used in Solid state laser pump sources,the carbon nanotubes(CNTs)with catalytic property,high specific surface area,strong adsorption capacity and high strength were intro-duced in pyrotechnic reagent Zr/KClO4 . The effect of carbon nanotubes on the thermal decomposition and light radiation perform-ance of Zr/KClO4(60/40)pyrotechnic reagent used in the pump sources was studied by differential thermal analysis technology and photoelectric detection technology. The results show that the addition of CNTs has a significant impact on the thermal decom-position characteristics and light radiation energy of Zr/KClO4 . With increasing of the CNTs,the combustion rate and exothermic quantity of the pyrotechnic reagent gradually increase,and the melting endothermic peak of the pyrotechnic reagent decrease and tend to disappear. However,the light radiation energies reveal the trend of firstly increases and then decreases. When the mass percentage of CNTs in the pyrotechnic reagent is 0.50%,the total radiation energy of the pyrotechnics can reach 1830 J·g-1. The effective radiation energy within the three strong absorption bands of Nd:Yttrium Aluminum Garnet( YAG)laser gain medium, that is(590 ±10)nm,(750±10)nm and(808±10)nm,can be increased by 41%,25% and 31%,respectively.
