| 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。

| Abstract: | 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. |
