An optical energy transmission system having an energy-emitting unit is provided. The energy-emitting unit has a laser radiation source for generating an energy-transmitting laser beam and an aiming device for aligning the energy-transmitting laser beam relative to an energy-receiving unit which includes an optical/electrical converter, which converts the energy of the energy-transmitting laser beam into electrical energy. The converter has at least one converter element having a plurality of surfaces which reflect the energy-transmitting laser beam and which are arranged relative to one another such that the impinging energy-transmitting laser beam is deflected by one of the reflective surfaces to another one of the reflective surfaces. At least some of the reflective surfaces are formed by a conversion unit which reflects one part of the impinging laser beam and absorbs the other part thereof in a photovoltaic element, and in the process converts the optical energy into electrical energy.
