Thermal effect analysis of all-solid-state solar pumped laser

  • 摘要: 太阳光泵浦激光器是将太阳光直接转化为激光的装置,具有能量转换环节少、效率高、结构简单可靠、性能稳定以及无污染等优点。对应用于空间环境(4 K)的全固态太阳光泵浦激光器进行了建模,并对泵浦太阳光收集阶段进行了热效应分析。先后考虑两种安装底座和四种太阳光线偏转情况,运用ANSYS Workbench@热分析软件分别进行了稳态热分析。针对第一种情况得到的可行性验证,提出了下一步的改进优化意见,并初步设想进行实际模型搭建和测试。针对第二种不可行情况,提出了几种可能的改进措施,并对未来的工作进行了展望。该研究为太阳光泵浦激光器在空间环境中的实际应用提供了一种全新的、采用全固态传导冷却方式温控系统的可行方案,为未来空间太阳光泵浦激光器能够得到实际应用提供了研究资料。

     

    Abstract: The solar-pumped laser is a device that directly converts the sunlight into the laser. It has the advantages of less energy conversion, high efficiency, simple and reliable structure, stable performance and no pollution. An all-solid-state solar-pumped laser for the space environment (4 K) was modeled, and the thermal effect of the pumped solar collection phase was analyzed. The steady-state thermal analysis was carried out by using ANSYS Workbench@ thermal analysis software, considering two mounting bases and four solar deflection conditions. According to the feasibility verification of the first case, the suggestions for further improvement and optimization were put forward, and the actual model building and testing were preliminarily envisaged. In view of the second infeasible case, several possible improvement measures were put forward, and the future work was prospected. This study provides a new feasible scheme of temperature control system with all-solid-state conduction cooling for the practical application of solar pumped laser in space environment, and provides research data for the practical application of space solar pumped laser in the future.
