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.
