Modular spacecraft is one of the directions of development of the future spacecraft, in which the technology of wireless power transmission between modular spacecraft is the key tech- nology of modular functional applications. According to the energy allocation requirements of dis- tributed cluster, the technology of the wireless power transmission is researched in the paper. Firstly the requirements of laser energy transmission technology are studied; then the establish- ment of a framework model and design for the constituent modules of the system, and the analy- sis of key technologies of laser wireless power transmission system（LWPTS） have been done. And finally we finish the simulation and experimental verification on the basis of laser energy transfer system, and get ideal access to the optical-electro conversion efficiency. With the progress of the technology, it can support the development of modular spacecraft.
