Abstract

A power beaming system includes a power beam transmitter arranged to transmit the power beam, and a power beam receiver arranged to receive the power beam from the power beam transmitter. A power beam transmission source is arranged to generate a laser light beam for transmission by the power beam transmitter from a first location toward a remote second location. A beam-shaping element shapes the laser light beam, at least one diffusion element uniformly distributes light of the shaped laser light beam, and a projection element illuminates a power beam receiving element of predetermined shape with the shaped laser light beam. At the power beam receiver, a diffusion surface diffuses a portion the power beam specularly reflected from the power beam receiver.
