摘　　要：为了研究Cr,Nd:YAG陶瓷作为太阳光抽运材料的可行性,采用光纤光谱仪实际测量了太阳光谱及其吸收光谱,计算了吸收系数曲线,以及Cr,Nd:YAG陶瓷吸收谱与太阳光谱的匹配程度,并在一定假设条件下,计算了介质的阈值抽运功率密度。结果表明,Cr,Nd:YAG陶瓷在可见光和近红外波段具有较宽的吸收带,其各个吸收带的总能量占太阳常数的38.44%,达到了很高的光谱匹配程度,证实了Cr,Nd:YAG陶瓷是太阳光抽运激光器工作物质的理想选择。In order to study the feasibility of Cr, Nd：YAG ceramic used for solar-pumped lasers, the absorption spectra of Cr,Nd：YAG ceramic and solar spectrum were measured with a fiber optic spectrometer actually, the absorption coefficient curve was calculated, the percentage of the solar energy which could be absorbed by Cr, Nd ： YAG ceramics was calculated. In an assumed condition, the threshold of pumped power density of the medium was calculated. The results show that the Cr,Nd：YAG ceramic have broad absorption bands at visible light and near-infrared band and the matching degree reached 38.44% , so Cr,Nd：YAG ceramic can be chosen as the most suitable medium for solar-pumped lasers.
