| 摘 要： | 为了提高化学激光体系(AGIL)中F原子的产率，采用直流放电引发方式，对棒式电极的放电特性进行了研究。在对NF3/He混合气体进行解离时，通过选择不同平衡电阻，得到了3 kW左右的放电注入功率。用光谱分析仪对F原子产率进行了测量。通过拟合计算可得:一个NF3分子能够解离出1.3～1.5个F原子。

| Abstract: | Annular subaperture test method has been developed for low cost and flexible measurement of large,fast aspheric surfaces without any special elements.The measurement principle of this method is simply introduced.The two representative algorithms based on discrete phase values and Zernike polynomials are numerically analyzed,and the result of primary experiment is provided.The results show that the method is feasible and provided that the potential for testing large aspheric mirror.According to the integrative analysis of the above research results,the experimental scheme of testing meter-class aspheric mirror with annular subaperture method is presented. |
