In the paper, a kind of distributed laser-powered system is constructed. The system can transmit power with laser beam directed to the photovoltaic cells by the beam-steering lens from the semiconductor laser. At the distance of 10 m between the emitter and receiver, the light-electricity transmission efficiency is studied by experiments with this system in the different situations, using single wavelength or different wavelength laser of three kinds to transmit power, and a preliminary exploration is implemented for the wireless energy transmission at the distance of 150 m. At the same time, the design of the system and the energy consumption are analyzed.
