摘要：A simulation model of a space-based solar laser system to transfer the power onto the earth is carried out. The system consists of a solar-pumped laser by a concentration system installed on a satellite. The resulted laser beam is re-directed onto the earth surface, where it can be used to generate power. The intensity and the divergence of the laser are calculated in order to obtain the suitable solar laser system as a payload on the satellite that matches and the terrestrial applications. According to our model, around 40 kW laser can be obtained by a frequency-doubled Nd:YAG laser rod which has a radius of 5 cm and a length of 10 cm, when we use the direct solar pumping via parabolic dish of a radius 100 m and a focal length 121 m accompanied with a 3D-CPC of an acceptance angle of 30°.
