免调试激光器与谐振激光自适应无线传能技术(特邀)

Alignment-free Laser and Resonant Laser Adaptive Wireless Power Transmission Technology(Invited)

作为最具代表性的定向能载体,激光可用于高功率、长距离的无线能量传输。传统上激光无线传能一般通过跟瞄系统实现,而近年来发展的谐振激光自适应无线传能技术提供了一种无需跟瞄的新解决思路,受到广泛关注。文中分析比较了这两种方法的特点,展望了未来发展趋势,并对后者的核心免调试激光器的实现方法进行了总结。

As the most representative directed energy carrier,the laser can be utilized for high-power and long-distance wireless power transmission.Conventionally,the wireless laser power transmission requires complex and expansive acquisition,tracking and pointing(ATP)system to deliver the laser to the receiver.Recently,there emerges the novel resonant laser power transmission technology.With the laser resonating between the power trans-mitter and the receiver,the beam is directed to the receivers automatically,without the necessity of the ATP system.The strengths and the weaknesses of the two different technologies are analyzed and compared,and the develop-ment is prospected.The development of alignment-free laser,which is the essential of the resonant beam wireless la-ser power transmission approach,is also summarized.
