Abstract
A transmitter unit for wireless transmission of power by way of a bundled laser beam is described. The transmitter unit has a laser fiber bundle having a plurality of laser fibers, wherein each laser fiber is designed to emit a laser beam; positioning optics for adjusting an emission direction of the bundled laser beam; a field lens and a primary lens. The plurality of laser fibers is designed to emit a laser beam from each, passing through the positioning optics, the collimator lens and the primary lens, in this order, so that the laser beam emitted by the transmitter unit is emitted in bundled form. A particularly efficient device with an unlimited flight time and a large radius of use is achieved by the hybrid drive with solar power and laser power from the ground and temporary storage of the power in batteries.
