摘　　要：激光技术在航天工程中具有重要的应用。对激光技术在航天材料加工、航天器空间环境效应地面模拟试验和航天器有效载荷上的应用进行了分析;对航天工程在激光晶体材料、激光薄膜材料、激光透明陶瓷材料及激光光纤材料等的需求和对策进行了探讨;对激光器系统在空间真空、温度交变、粒子辐射、太阳电磁辐射、等离子体以及振动等环境下的适应性及对策进行了研究。给出了建议,即应该进一步加强强激光材料的基础科学研究,研制性能优异的激光材料与有效载荷,加强激光器系统与载荷的空间环境适应性研究。Laser technology has important application in space engineering. In this paper, applications of laser technology in spacecraft material processing, space environmental effect ground simulator test and spacecraft payload were discussed. The requirements and countermeasures of space engineering on laser crystal, laser thin film, laser transparent ceramic and laser fiber materials were discussed. The adaptibility and countermeasures of laser system in space environments as vacuum, temperature altering, particle radiation, solar electromagnetic radiation, plasma and vibration was studied. Key materials and space environment adaptibility of laser technology on space engineering were analyzed. Some advices were advanced such as strengthening the basic scientific study on laser material, preparing the laser materials and payload with excellent performance and strengthening the study on adaptibility of laser system and payload in space environments.
