Abstract
A wireless optical charging system according to the present invention includes a transmitter which transmits a laser beam as light with an energy increased by the resonance; and a receiving unit which receives light transmitted from the transmitter and converts an energy for some light among the received light into an electric energy to charge devices. Accordingly, the laser resonance power transfer technology is used to solve the limitation of the distance and harmfulness to the human body.
