    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 Cm decreases with increasing the pulse energy for single pulse tests and pulse duration of about 1μs.Either higher or lower frequency will reduce Cm in multi-pulse tests,which suggests an optimal frequency for the maximum Cm.As to the work time,the longer the work time is,the less the Cm will be.
