| 摘要: |
| 对于高能激光器来说, 晶体材料输出窗口因吸收致热而无法正常工作。自由旋涡气动窗口利用超音速自由旋涡来密封低压的激光腔。本文提出了确定气动窗口所需自由旋涡气动特性的过程, 讨论了特征线方法在非对称超音速喷管设计中的应用, 该喷管被用来产生自由旋涡流动。 |

| Abstract: |
| The crystal window of high-power laser can not work in gear because of the heat caused by absorption of high-power beam. The supersonic free-vortex segment is usually employed to seal low-pressure laser-cavity. In this article the procedures are described for determining free-vortex segment properties. Characteristics method is used to design nozzle which produces free-vortex segment. |
| Keywords: free-vortex asymmetric nozzle characteristics |
