Influence of rotation state of irregular shape target on laser ablation driven impulse

Laser ablation driven is one of the most promising active debris removal technologies. However, the rotation state of the target has a very complicated impact on the effect of laser ablation, which is one of the problems to be solved. In this paper, the laser driving impulse under the continuous irradiation for rotating plate target was analyzed by theoretical calculation, and the effect of pulse frequency and target rotation speed on it was also discussed. And with the surface triangulation and three-dimensional reconstruction calculation method, the magnitude and direction of laser driving impulse under the continuous irradiation for rotating typical shape target, such as cylinder, cuboid and cone, and irregular shape target were analyzed under different pulse frequency and different rotational angular velocity. The results show that the rotation of the target will make the driving effect of continuous pulse laser change periodically with the increase of pulse number; Its magnitude and periodic variation are affected by the rotation speed, pulse frequency and the shape of itself; By the rational selection of laser irradiation strategy, the influence of rotation on the impulse direction of laser pulse continuous irradiation can be minimized or eliminated.
