连续波DF激光器高腔压运转的数值研究
-
摘要: 对以C2H4作燃料、以He作稀释剂的燃烧驱动连续波DF化学激光器进行了模拟计算,着重研究了激光器在高腔压条件下的性能。通过比较两种具有不同喷管家结构的DF化学激光器的高腔压运转下的平均腔压、激射强度、输出耦合功率和化学效率,指出高腔压运转对喷管结构的要求。Abstract: Numerical simulation of the combustion driven CW DF chemical laser are performed, the performance of C2H4/He laser under high cavity pressure is studied. The optical cavity pressure, lasing intensity, outcoupling power and chemical efficiency of different nozzle arrays are given. The results showed that: high cavity pressure require not only high pressure of combustor but also optimal nozzle arrays.
