摘要 为了实现高效的太阳光泵浦系统,有必要设计一种兼具低热冲击和高聚光量的泵浦腔。利用TracePro软件建立菲涅耳透镜、瓶形泵浦腔二级系统,通过优化确定了最佳入窗口径、入窗位置、出窗口径、瓶腰直径、瓶腰位置、晶体棒长。通过理论计算得出了长度为60 mm晶体棒的泵浦阈值功率为4.568 W/m^(2),最佳系统结构的输出功率为18.21 W,热透镜焦距为31.0 cm。在与锥形腔的比较中计算得出两种腔形下晶体棒的轴向温度分布曲线,通过对比表明,瓶形腔在减少热冲击和提高抽运光均匀性上具有明显的优势。本文的优化设计为后续实验提供了新思路。 In order to achieve an efficient solar pumping system,it is necessary to design a pumping cavity with both low thermal shock and high light concentration.In this paper,the two-stage pumping system of Fresnel lens and vase shaped pumping cavity is established by using TracePro software,and the optimum diameter of entering window,position of entering window,caliber of exit window,diameter of vase waist,position of vase waist and length of crystal rod are optimized for high efficiency and more homogenous pump energy distribution.Through theoretical calculation,the pump threshold power of 60 mm crystal rod is 4.568 W/m^(2),the output power of the optimal system structure is 18.21 W,and the focal length of thermal lens is 31.0 cm.In comparison with the conic cavity,the axial temperature distribution curves of the crystal rod under the two kinds of cavity shape are obtained.By comparison,it is found that the vase cavity has obvious advantages in reducing thermal shock and improving pump light uniformity.The optimal design of this paper provides a new idea for follow-up experiments.
