Abstract: A system for supplying power wirelessly to a remote mobile device including (i) a transmitting unit for directing radiation into the region of the mobile device, the transmitting unit having a gain medium with a front surface directed towards the space, and a retroreflector on its back surface, and (ii) a receiver unit connected with or attached to the mobile device for receiving radiation transmitted from the transmitting unit. The receiver unit includes (i) a retroreflector for reflecting part of the radiation received from the transmitting unit back in the direction of the transmitting unit, where it is amplified and retransmitted back in the direction of the receiver unit, and (ii) a power detection element for absorbing that part of the radiation not reflected by the retroreflector, and converting it to electrical power for use by the mobile device. Modulation of the transmitted beam enables it to transmit data also.

Abstract: An optical power beam transmission systems, with a directional light transmitter and receiver. The transmitter contains an amplifying laser medium, and this together with a retroreflector in the receiver, forms a laser resonator. When lasing sets in, the receiver can extract optical power through an output coupler and convert it to electrical power. The gain medium may be a disc having a thickness substantially smaller than its lateral dimensions. The laser resonator is operated as a stable resonator to ensure safe operation. This is achieved by use of an adaptive optical element, for reducing the diameter of the energy beam impinging on the gain medium, thereby increasing the overlap between the energy beam and the gain medium. As the transmitter-receiver distance is changed, such as by movement of the receiver, the adaptive optical element focal length changes to ensure that the cavity remains within its stability zone.
