【Abstract】 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.更多还原
