Wireless Laser Power Transmission: A Review of Recent Progress

Laser power transmission (LPT) is one of the most promising technologies in the long-range wireless power transfer field. LPT research has been driven by the desire to remotely power unmanned aerial vehicles, satellites, and other mobile electric facilities. However, the low overall efficiency is the main issue that limits the implement of high-intensity laser power beam (HILPB) system. As seen from the contemporary understanding of efficiency...
