We have experimentally studied the characteristics of a supersonic cw chemical HF laser with a flat nozzle array based on a nozzle – nozzle reagent mixing scheme operating with the use of F₂ – D₂ – He and NF₃ – D₂ – He fuel compositions in an atomic fluorine generator. The active medium flow field pattern, its gas-dynamic characteristics, and the laser radiation spectrum are considered. The comparison of these characteristics has made it possible to establish a strong impact on the flow field (lasing zone length) of the chemical composition of the combustion products from the atomic fluorine generator. The gas-dynamic parameters of the active medium formed by using a NF₃ – D₂ – He fuel have turned out to be less acceptable in terms of the gas flow pressure recovery than in the case of F₂ – D₂ – He fuel, while the radiation spectrum was more preferable from the viewpoint of passing through the atmosphere.

我们实验研究了具有平面喷嘴阵列的超音速连续化学 HF 激光器的特性，该激光器基于喷嘴-喷嘴试剂混合方案，使用 F ₂ – D ₂ – He 和 NF ₃ – D ₂ – He 燃料成分在原子氟发生器。考虑了活性介质流场模式、其气体动力学特性和激光辐射光谱。这些特性的比较使得可以确定对来自原子氟发生器的燃烧产物的化学成分的流场（激光区长度）的强烈影响。使用NF ₃ – D _{2形成的活性介质的气体动力学参数- 与 F 2} - D ₂ - He 燃料相比，He 燃料在气流压力恢复方面的可接受性较差，而从穿过大气的角度来看，辐射光谱更可取。
