PROBLEM TO BE SOLVED: To transmit power in space from transmission equipment to reception equipment. SOLUTION: A laser diode (12) selectively outputs a low-power dummy beam for detection of reception equipment and a high-power laser beam for transmission. The output laser beam of the laser diode (12) is emitted out of the transmission equipment (10), with its beam spread adjusted by a lens (16). Four corner cube reflectors (CCR) (44-50) arranged around a light receiving element (42) reflect the dummy beams for detection of reception equipment from the transmission equipment (10). A controller (30) adjusts the focus of the lens (16), following the reflected beam from the reception equipment (40), and controls the direction of laser emission by an optical axis deflector (32). After these adjustment, the controller (30) outputs a laser beam for transmission from the laser diode. The receiving element (42) of the reception equipment (40) receives the laser beam for transmission from the transmission equipment (10) and converts it into electric energy.
