Laser technology and laser system has more and more important implication in spacecraft engineering. But different from ground environments, space environments include vacuum, extreme temperature and thermal cycling, space radiation environment such as electron, proton, heavy ions, ultraviolet, contamination, and so on. Space environments may have damage or threaten to the space laser system, especially to their optical devices. So the influence of space environments on the laser damage of space laser system should be studied. In this paper, space environments of space laser system encountered is introduced firstly, and then the influence of space environment on space laser system is discussed. Thirdly, the damage mechanism of space environment on laser damage is analyzed. At last, some works or countermeasures were proposed to improve the laser radiation damage threshold of laser system in space environments.
