| 摘 要： | The optimum parameters for laser propulsion are discussed, such as laser induced pressure on targets, interaction parameters (Cm, Isp) and optimum laser intensity Is, etc. It is verified that the larger laser power density will induce higher thrusting force. It is also found that, to drive a 1.010-kg target during confined laser ablation in vacuum and a 17.45-g one during direct laser ablation in air at the standard pressure, the needed minimum power intensities are on the same order of magnitude.
