The wire connection under harsh environmental conditions (high temperature or high radiation) results in many limitations. Laser power transmission (LPT) is regarded as a convenient conduit for power delivery wirelessly. LPT has many benefits, which include zero electromagnetic interference, immunization from temperature and radiation, and long transmission distance. Based on the LPT structure, an LPT powered actuator system is proposed. The steady-state characteristic of the system is analyzed, and the result shows the steady-state characteristic mainly depends on the load torque. A robust speed control method is proposed by feedback of the DC motor speed to determine the laser on/off state to adjust the speed. The result indicates that in the analyzed-controllable range, the speed is stably controlled.

Laser power transfer (LPT) is one of the leading technologies in long-distance power transmission with its advantages such as enabling high power transmission and suitability for mobile applications. The transmitter part, which includes the laser diode (LD) and the driving circuit, directly affects system efficiency. Continuous wave (CW) lasers are used in studies due to their high power and continuous radiation. However, one of the main disadvantage of the mentioned system is the high cost of LD. In this study, the use of pulsed LDs in LPT applications is proposed because of their small size and low cost. On the other hand, appropriate operating point of pulsed LD is missing information in the literature. In order to contribute literature with this information, pulsed LD is used for LPT, and the effects of driving voltage amplitudes, frequencies, and duty cycles are analyzed to demonstrate the importance of determining the appropriate operating point of the pulsed LD and the potential use of pulsed LDs in LPT.INDEX TERMS Wireless power transfer, laser power transmission, laser diode, pulsed laser diode.

Recently, unmanned aerial vehicles (UAV) have been widely used in the military and civil fields. However, the battery power is a key factor that restricts the operation range of the UAV. Using wireless power transfer (WPT) technology to power UAVs can improve the endurance of UAVs and enhance their maneuverability and flexibility. In this paper, the WPT technology is divided into three types: near-field WPT technology, far-field WPT technology and solar-powered UAV. The developments, challenges and prospects of these three types of WPT technologies used to power UAVs are summarized. For each type of WPT technology, the basic working principles are first introduced. The development of each type of WPT technology, as well as the challenges and application prospects in UAV charging, is introduced. The related works consist of academic and industry research, ranging from prototypes to commercial systems. Finally, three types of WPT technology used in UAV charging are compared and discussed, and the advantages and disadvantages of each type of WPT technology are shown. The related research showed that using WPT technology to power the UAV is a promising way to enhance the endurance of the UAV.
