Because pulse repetition rate affected directly the momentum coupling coefficient of transversely excited atmospheric (TEA) CO<sub>2</sub> laser propulsion, a double pulse trigger, controlling high voltage switch of laser excitation circuit, was designed. The pulse interval ranged between 5 and 100 ms. The momentum coupling coefficient for air-breathing mode laser propulsion was studied experimentally. It was found that the momentum coupling coefficient decreased with the pulse repetition rate increasing.
