Abstract

The invention discloses a laser energy transfer system. By the aid of the laser energy transfer system, pointing accuracy between an emitting end and a receiving end can be improved, uniformity of light intensity distribution of the beam receiving end can be improved, and photoelectric conversion efficiency of a photoelectric cell is improved, so that energy transfer efficiency is effectively improved. The photoelectric cell of the energy receiving end is designed, a photoelectric cell unit 1 can align to light spots in real time, high conversion efficiency is kept, a photoelectric cell unit 2 and the photoelectric cell unit 1 pass optimal power tracking constant-pressure output units prior to parallel output, loss of light spot energy at the edges of the light spots is reduced, and maximum conversion efficiency is guaranteed. Moreover, a phase control array regulates beam phases to obtain uniform light spots, pointing of beams is controlled through a beam control device, high beam pointing precision is ensured, and energy transfer efficiency of the laser energy transfer system is improved effectively.

Description

technical field [0001] The invention relates to the technical field of energy wireless transmission, in particular to a laser energy transmission system. Background technique [0002] The energy module spacecraft and mission module spacecraft of the separation module spacecraft, emergency rescue equipment in the event of geological disasters and meteorological disasters, robots performing volcanic exploration missions, and electric aircraft far away from the base without landing conditions, etc., have different working and operating environments. It has the conditions to erect cables for power supply. Laser wireless energy transmission uses laser as the medium and does not need energy transmission lines to provide energy support to the target machine working in a specific environment so that it can successfully complete the assigned tasks. It is a key means to supply energy for the above-mentioned equipment. The core indicator is the conversion efficiency of electricity to ...
