【Abstract】 In this paper, the changes of laser power density and its correspondingly propulsive speed, with the changing depth of propulsion, have been given. Based on hydrodynamic methods, the ablation rate and the propulsive force on the debris, when the high-power pulsed laser irradiates on the space debris, have been derived. As one ingredient of the space debris, Aluminum, for example, the laser ablated mass, its corresponding mass ablation rate, the thrust on the debris, the momentum coupling coefficient, and specific ablation energy, have been simulated and calculated within one high-power laser pulse.更多还原
