Synergistic effect of laser radiation and space natural radiation environments on spacecraft

Spacecraft will be damaged by space radiation environments such as electron, proton, X-ray, gamma ray, ultraviolet, and so on. For laser system used in spacecraft, its laser materials and laser devices will be damaged by laser beam. Besides, surface materials of spacecraft can be damaged by high energy laser too. So, spacecraft materials and devices may be damaged by synergistic effect of laser radiation and space natural radiation. In this paper, space radiation environments are introduced firstly, and then synergistic mechanism between laser and space radiation environments are discussed. Thirdly, test method for synergistic effect of laser radiation and space natural radiation on spacecraft is analyzed. At last, some directions are suggested to improve the space environment adaptability of spacecraft in space radiation environments and space laser radiation environment.
