Abstract

The invention discloses a laser wireless energy transfer device and method. The laser wireless energy transfer device comprises a fiber laser source, an emission system and a laser battery; the fiberlaser source combines generated paths of single-frequency seed laser into a beam and outputs the combined laser beam; the emission system converts the combined laser beam into parallel laser and emitsthe parallel laser; and the laser battery receives the parallel laser and converts the parallel laser into electric energy. The output combined laser beam is large in power and satisfies a receptionrequirement of the laser battery, a light spot shape of the combined laser beam is adjusted from circular into oval, and the coupling efficiency between the combined laser beam and a laser cell panelis improved.

Description

technical field [0001] The invention relates to the field of energy transmission, in particular to a laser wireless energy transmission device and method. Background technique [0002] Laser wireless energy transmission is one of the important means of long-distance wireless energy transmission. Wireless charging needs. The core components of laser wireless energy transmission technology are lasers and laser batteries. The laser at the transmitting end emits a laser beam with a certain wavelength and certain technical requirements, which is collimated by the transmitting optical system and sent out through the space link. The laser battery at the receiving end receives the laser light, converts the input light energy into electrical energy through efficient photoelectric conversion, and supplies power to user equipment. [0003] At present, an important factor limiting the development of laser wireless energy transmission technology is the output power limitation of laser...
