A kind of space junk energy conversion device and method based on laser threat warner

The present invention relates to space junks to utilize technical field more particularly to a kind of space junk energy conversion device and method based on laser threat warner.The device includes device noumenon and the optical alignment mechanism being separately positioned on described device ontology, optical spectroscopic mechanism, optics working medium coupling mechanism and working substance supply mechanism, wherein the bottom of the optical alignment mechanism is arranged in the optical spectroscopic mechanism, and each optics working medium coupling mechanism connects one to one with each working substance supply mechanism respectively.The present invention is using space junk as the solid-state working medium of laser threat warner, it is interacted using laser with the space junk being collected into, cause space junk ablation and gasifies and ionize to form plasma, plasma deflagration wave compression space fractal surfaces generate thrust, to realize the recycling of space junk, have structure simple, energy Transform efficiency is high, the advantages of will not causing secondary pollution to space environment, may be directly applied to the in-orbit control of spacecraft.
