Abstract
A wireless laser power transfer system includes, in part, a transmitter and a receiver that form a wireless link. The transmitter, includes, in part, a first communication system, at least a first source of laser beam, and a controller adapted to vary power and direction of the laser beam and further to modulate the laser beam. The receiver includes, in part, a communication system adapted to establish a wireless link with the first communication system, at least a first photo-voltaic cell, and a controller adapted to demodulate and detect the power of the modulated laser beam received by the first photo-voltaic cell from the first source of laser beam. The system optionally includes at least a second source of laser beam controlled by the transmitter controller. The system optionally further includes a second photo-voltaic cell. The transmitter controller is further adapted to cause the second laser beam to strike the second photo-voltaic cell.
