摘　　要：为了提高激光传能的电到电转化效率，文章设计了一种激光传能系统，采用相位阵列提高光束接收端光强分布的均匀度同时提高激光发射端与光束接收端之间的瞄准精度，优化了光电池排列设计，增大了光电池对激光束的接收效率及光电转换效率，从而提高了激光传能的电到电转换效率。
Resource vehicle （RV） and mission vehicles （MV） of formation flying spacecraft are impractical to transmission electricity by wires. Laser power transmission, transmitting electrici- ty by laser wirelessly, is a clear candidate for formation flying spacecraft. In order to improve the electric-to-electric （E/E） efficiency of laser power transmission, a laser power transmission sys- tem is designed, in which laser intensity uniformity across all the photovoltaic （PV） converters connected in series, mechanical tolerances to aim and hold the lasers, mismatch between laser spot and PV converters are all enhanced. As a result, the electric-to-electric efficiency is improved.
