Abstract: Both laser communication and laser power transmission use laser as carrier and transfer information and power to remote device in space, which have natural commonalities in system composition. In one system, use laser beam transfer information and power simultaneously will optimize system composition and increase system efficiency. In this paper, laser wireless high-power and high-speed information simultaneous transfer technology is studied. Based on rocket wireless transfer need, a power and information prototype is developed which attain 25m transfer distance, 461W electric power and 500Mbps communication rate. It is provided solution for the development of information and power simultaneous transfer technology.
