本論文的研究目的是透過模擬並驗證一個使用平面型導光板作為太陽能集光器的新型太陽能雷射系統。本研究利用LightTools軟體建構一個平面型導光板太陽能集光器，透鏡陣列中的每個透鏡皆對應到一個在導光板底部的空氣凹槽微結構，透過內全反射的特性將光線引導收集並入射雷射增益晶體，再透過LASCAD軟體的優化與驗證雷射系統的特性。研究結果發現在太陽光垂直入射集光器的模型上，光學效率可以由其他研究的81.9%提升至我們模型的87.33%；而在太陽光斜向入射集光器的模型上，光學效率可以由其他研究的64%提升至我們模型的93.45%。在太陽能雷射的部分也成功透過平面型導光板太陽能集光器建構出新型且相對輕薄的太陽能雷射系統，雷射系統的斜率效率可以由其他研究的2.3%提升至我們模型的10.06%。

The purpose of this research is to simulate and verify a new solar laser system using a planar lightguide as a solar collector. This study uses LightTools software to construct a planar lightguide solar collector. Each lens in the lens array corresponds to an air dimple microstructure at the bottom of the planar lightguide, which guides the collected light into the gain medium through the characteristic of total internal reflection. Optimize and verify the characteristics of the laser system by LASCAD software. The results of the study found that the design of the concentrator has a good performance compared with other studies. In the part of the solar laser system, it has also been successfully verified that the laser can reach the light-emitting condition through this new and relatively thin planar lightguide light-collecting system.
