摘要
建立并分析了太阳光点聚焦型菲涅耳透镜的理论模型。提出了适用于太阳光泵浦激光器的设计方法。综合考虑会聚总功率和功率密度提高倍数两个因素,合理设计了菲涅耳透镜口径,相对孔径以及环形小棱镜的宽度(环距)三个参数,获得了用于太阳光泵浦激光器的菲涅耳透镜。
The large aperture Fresnd lens design principle for solar-pumped laser is presented.The factors of focal power and improvement of power density have great influence on solar-pumped laser operation.The parameters of lens aperture,rela- tive aperture and groove spacing are discussed for two factors.The principle of calculated Fresnel lens for solar-pumped laser is also given.
