Claim:
1. A system for transmitting power wirelessly to a remote device disposed in a space, comprising: a transmitting unit comprising a gain medium having a front surface adapted to emit radiation generally towards said space, and a rear surface having a retro-reflector in optical association therewith, the distance between any two opposing points on opposite edges of said front surface of the gain medium being more than the distance between said front and rear surfaces, such that said radiation can be amplified by said gain medium and emitted from said front surface over a wide range of angles; and a receiver unit associated with said device and adapted to receive said radiation transmitted from said transmitting unit, and comprising a retro-reflector adapted to retro reflect a first portion of said radiation received from said transmitting unit back in the direction of said transmitting unit, such that said transmitting unit amplifies said radiation reflected back from said receiver unit and retransmits it in the direction of said receiver unit, and adapted to transmit a second portion of said radiation, such that it is utilized by said device.
