| 摘要: |
| 简述了燃烧驱动大功率连续波DF化学激光器的发展现状。比较了HYLTE与TRIP两种喷管的结构参数，总结了两种喷管的性能差异。采用数值模拟手段，参考相关试验数据，计算了典型增益分布对应的共焦非稳腔输出光束模式。从大功率DF激光器研制存在的光斑均匀性和腔镜负载两个难题的角度，结合喷管制造工艺要求，认为HYLTE喷管较TRIP喷管更适用于大功率DF激光器。 |

| Abstract: |
| Developing status of combustion driving high power continuous wave Deuterium Fluoride(DF) chemical laser has been briefly presented. Structure parameters of HYLTE (Hypersonic, Low Temperature) nozzle and TRIP nozzle have been comparatively analyzed. Performance difference between the two kinds of nozzles has been summarized. Based on some correlational reported test data, output transverse modes of confocal unstable resonator corresponding to typical gain coefficient distribution along the flow field have been simulated by using numerical method. Considering technical maturity and reliability, we conclude that employing HYLTE nozzle is more appropriate than TRIP nozzle in research and development of high power DF laser concerning the two hard problems: uniformity of beam spot and load of mirrors. |
