大功率高速激光无线能量信息同传技术

激光通信及激光能量传输技术都以激光为载体，进行空间传输，将能量和携带信息传递给远端设备，在系统构成上具有天然共同点，因此，在同一套系统内实现激光通信/传能两种功能，必将成为未来系统能源信息传输的有效手段，将优化系统构成，提高系统效率。文章研究了激光无线能量信息同传技术，对激光能量信息同传机制、同传机制下激光信号调制解调、高效率光电转换技术，提出高效能量信息同传系统设计方案，研制了火箭地面激光传能通信一体化样机，实现25m传输距离，激光无线供电461W，激光无线通信速率500Mbps，为下一步高效激光无线能量信息同传系统发展提供解决思路。

Laser wireless high-power and high-speed information simultaneous transfer technology

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.
