Abstract: Wireless power transmission (WPT) technology includes two technical approaches: Micro-wave wireless power transmission (MWPT) and laser wireless power transmission (LWPT). In this paper, the basic concepts of LWPT technology was introduced. And the development history and current situation of LWPT technology at home and abroad were summarized. The main research contents of LWPT technology and the development direction and possible application of LWPT technology were reviewed. Comparing the situation at home and abroad, domestic LWPT research is still in the early stages of theory and application, and more investment is needed to promote its development.
