摘　　要：通过建立一套氟化氢泛频化学激光器实验系统 ,介绍了一种新型高超音速低温喷管的结构及其实验参数设置方法 ;对喷管性能进行了测试 ,并将实验结果同数值模拟结果进行对比 ,找出了改善喷管性能的方法。由该喷管构成的激光系统已顺利出光。The employment principle of HF(hydrogen fluoride) overtone chemical laser is described in brief in the article, and a new high supersonic lowtemperature nozzle manufactured is introduced in detail, including its structure and the experimental parameters set method. In the experiments on the laser, gain is observed. Several valuable results can be concluded by analyzing the measured experimental data. Test and measure methods in nozzle experiments established and the numerical simulation method of value are introduced.
