Utilizing drones in many applications such as video and photography, farms, search and rescue operations, construction industry for mapping and site monitoring has increased. However, their operating time is limited according to the capacity of their batteries. Therefore, many researchers attempt to enhance the operating time of drones. In this study, to the best of the authors' knowledge for the first time, the feasibility assessment of a laser-based wireless power transfer (WPT) mechanism is theoretically investigated on drone applications to increase their operating time. In this method, drones can be charged during operation wirelessly at a considerable distance with acceptable efficiency. The Analytical code is developed in Engineering Equation Solver (EES) software. The acquired results for the main components of the system have a good agreement with published papers of other researchers. In this study, three commercial photovoltaic (PV) materials were evaluated. The results show that an equipped drone with laser-based WPT system is able to approximately receive net power of 73.5, 62.6, and 33.2 W at a 500 m distance by GaAs, CdTe, and c-Si PV materials, respectively, while the laser module consumes around 600 W electrical power. Moreover, since the optical power of the laser is concentrated on PV panel, a two-phase cooling system is suggested for PV panel to reduce the temperature of the under radiate area. Results demonstrate that the temperature of GaAs PV material without a two-phase cooling system is approximately three times more than the temperature of PV panels with a two-phase cooling system at high power transfer rates.

在视频和摄影、农场、搜索和救援行动、建筑业进行测绘和现场监控等许多应用中使用无人机的情况有所增加。但是，它们的运行时间受到电池容量的限制。因此，许多研究人员试图提高无人机的运行时间。在这项研究中，据作者所知，首次对基于激光的无线电力传输 (WPT) 机制的可行性评估在无人机应用中进行了理论上的研究，以增加其操作时间。在这种方法中，无人机可以在操作过程中以可接受的效率在相当远的距离进行无线充电。分析代码是在工程方程求解器 (EES) 软件中开发的。系统主要部件的获得结果与其他研究人员发表的论文有很好的一致性。在这项研究中，对三种商用光伏 (PV) 材料进行了评估。结果表明，配备基于激光的 WPT 系统的无人机能够在 500 m 距离处分别通过 GaAs、CdTe 和 c-Si PV 材料接收大约 73.5、62.6 和 33.2 W 的净功率，而激光模块消耗大约 600 W 的电力。此外，由于激光的光功率集中在光伏面板上，建议光伏面板采用两相冷却系统，以降低辐射不足区域的温度。
