Abstract
Systems and methods are described that facilitate refueling a vehicle with electrical energy by targeting receiver thereon and pointing a high-intensity laser source at the receiver. Vertical multi-junction (VMJ) photocells receive the laser energy and convert the laser energy into electrical energy. The laser source can operate at a range of output power levels depending on the vehicle's energy needs. The laser source can be pulsed or continuous near-infrared laser source. A heat exchanger can be coupled to the receiver to dissipate laser energy not converted into electrical energy. If the vehicle has a propeller, the heat exchanger can be mounted to the vehicle in the propeller wash path.
