Abstract

The effects of main laser parameters, such as pulse energy, pulse duration, frequency, and work time on laser propulsion of "air-breathing mode", are investigated experimentally with a high power and high repetition frequency TEA-CO2 pulsed laser. The results show that the momentum coupling coefficient C_(m) decreases with increasing the pulse energy for single pulse tests and pulse duration of about 1 ?s. Either higher or lower frequency will reduce C_(m) in multi-pulse tests, which suggests an optimal frequency for the maximum C_(m). As to the work time, the longer the work time is, the less the C_(m) will be.
