| 摘要: |
| 为了研究HF化学激光器的背压对激光器输出性能的影响，同时也为即将开展的基区引射式HF化学激光器实验提供参考数据，针对某一特定结构的HF激光器，通过改变激光器背压进行出光实验，得到了不同背压条件下的输出功率和激光光斑。结果显示，该激光器形成有效激射的背压上限为4kPa，同时，扩散混合对腔压的依赖非常严重，相比之下，射流混合在较高的背压条件下仍然能够形成激射。 |

| Abstract: |
| In order to study the effect of background pressure on the output performance of HF laser, and to provide referenced data for the “Base-ejecting” HF chemical laser, a series of experiments were conducted with different background pressure for a certain HF laser. From them, the output power and faculae were obtained. The results reveal that, the upper limit of background pressure for lasing is 4 kPa. In addition, the dependence of lasing with diffusional mixing on the cavity pressure is deep, on the other hand, lasing will be generated in high background pressure with injection mixing. |
