全气相化学激光体系的直流放电研究
DC discharge for the all gas-phase iodine laser

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: A DC discharge method is introduced to improve the production of F atom for all gas-phase iodine laser(AGIL). Characteristics of the DC discharge are studied for the usage of cylinder electrode. About 3 kW input power is obtained when dissociating the mixture of NF3 in He by different balance resistance. Production of F atom is measured with spectrometer(CCD) and the production of F atom is about 1.3~1.5 with one NF3 molecule.-
