摘要: 太阳光泵浦式激光器将非相干的太阳光直接转化成相干的激光,既可以提高转换效率、节省能源,又可以使得整个装置简化.由于太阳光功率密度达不到直接抽运激光器的需求,所以需要高效的聚光系统,来实现泵浦激光器所需的阈值要求.本文利用菲涅尔透镜和锥型场镜组成的高效聚光系统,使太阳光可以更高效的耦合进入泵浦腔,抽运Nd ∶ YAG 晶体,通过模拟得到聚光系统收集的太阳光,聚光比达到104 ,增大了泵浦率,产生较高的激光输出功率.

Abstract: A direct conversion of concentrated solar radiation into a coherent laser beam can be used to improve the conversion efficiency because of the design simplicity on structure. To surpass the lasing threshold,the solar radiation needs to be highly concentrated. The high efficient concentration system is composed by the Fresnel lens and the cone-channel condenser. The solar concentrated by the concentrator system is coupled into the chamber pumping Nd ∶ YAG laser media. The concentrator ratio is 104,improving the output of laser.

Key words: lasers, solar, Fresnel lens, cone-channel condenser
