| 摘要: |
| 减小现有电激励HF/DF化学激光器放电管的内径有利于多模块集成，并可能有利于提高激光器性能。对内径分别为28mm、20mm、16mm的三种放电管的辉光放电特性及激光器运行参数进行了实验研究。注入NF3后，三种放电管中等离子体发生了不同程度的收缩现象。内径20mm放电管收缩比率最小，而且总耗气量最低，激光器输出功率和电光效率最高，副He注入对激光器输出功率提升作用最显著。通过分析对比实验结果，提出等离子体的稳定性和体积大小，是判断放电管性能的两个直观因素。 |

| Abstract: |
| Reducing the diameter of the discharge tube used in the discharge driven HF/DF chemical laser is useful for integration of multi- module, and may be useful for promoting the performance of the laser as well. The glow discharge characteristics and laser operated parameters of three different discharge tubes were experimental studied, and the diameter of the discharge tubes was 28mm, 20mm and 16mm, respectively. When NF3gas was injected, the plasma necking phenomenon occurred in all three discharge tubes. For the laser which used the 20mm diameter discharge tube, the plasma necking phenomenon was the weakest, the total consume of working gas was the least, the output power and the electro-optic transfer efficiency were the highest, and the laser output power promotion effect by secondary He was the most outstanding. Through comparison, it is suggested that the stability and volume of the plasma are two intuitionistic parameters for judging the performance of discharge tubes. |
