摘　　要：以机理研究为主线对激光预处理技术进行了回顾。从材料类型和激光参数等方面对预处理的理论与实验结果进行归纳分析,得出预处理效果取决于缺陷在热作用下的演变规律的结论。重点分析了三种定量模型,对比了各模型的优缺点,并指出了未来预处理模型的发展趋势。最后结合机理研究的新方法、工业化应用和进一步提高增益等问题对预处理技术进行了展望。Focusing on the intrinsic mechanism, research progress in laser conditioning of optical materials is reviewed. In terms of material types and laser parameters, theoretical and experimental conditioning results are concluded and analyzed. As a result, the conditioning effects is determined by the evolution rule of defects under heat. Three quantitative models are discussed in detail. Their merits and demerits are compared, and the modeling tendency of conditioning is pointed out. Finally, the direction of future work is introduced considering problems such as novel research methods, industrial application and improving conditioning gain.
