Outline of Final Research Achievements |
One of the most hopeful method to remove space debris is the method using laser ablation. High repetitive pulse irradiation with the optimum laser energy density is expected to be more effective to produce large impulse than single pulse irradiation with giant laser energy. However, impulse decreases as the laser pulse number increases. As a result of this study, it was found that the main causes of the decrement were the decrement of the laser energy density at the irradiation spot and wide spreading particles both which were caused by the change of surface shape.
