摘要
设计了基于激活反射式钕玻璃激光放大器的抽运反射结构。反射式钕玻璃激光放大器的抽运结构与传统透射型阵列式片状放大器(MSA)不同,为提高氙灯背向抽运光的利用效率,抽运反射罩的排布与面型需要与结构形式匹配的优化设计。针对反射式钕玻璃激光放大器的独特结构形式,通过Matlab模拟仿真,提出了一种新型短翼仿渐开线型反射罩面型。用光学仿真软件TracePro进行配光追迹,得到了新型抽运反射罩的模拟传输效率,比平板反射器的模拟结果高17.58%。通过氙灯抽运的全尺寸反射式钕玻璃激光放大器实验装置,对优化结果进行了验证,实际效率提高约15.19%。
Abstract
A type of pump reflector for large aperture active mirror slab amplifier is designed. The amplifier is different from the conventional multi-segment-amplifier (MSA). The reflector should be specially designed to improve the efficiency of the pump Xe-lights. For the unique structure, the theoretical optimized curve function is calculated by Matlab. TracePro is used to simulate the designed reflector based on the optimized function, and get the theoretical efficiency of the reflector. Compared to the flat reflector, the efficiency is 17.58% higher. A 11 experiment is designed and used to test the performance of the reflector, whose efficiency is 15.19% higher than the flat one.
