摘　　要：采用波长为355nm的3倍频Nd:YAG激光器对纸本书画主要材料宣纸上产生的霉菌进行了激光清洗实验研究。清洗机理主要是利用激光光子与霉菌微生物大分子的相互的作用产生光分解效应以及热效应。实验的结果表明,选择适当的激光能量密度,可以实现对霉菌的清洗而不会损伤宣纸基底。激光清洗技术可以安全有效地去除宣纸上的霉菌。Laser cleaning of the mildew on rice paper with ultraviolet frequency tripled Nd：YAG laser has been studied in this paper. The mechanism of laser cleaning is the ablation and thermal effect through the interacting of photon and mildew. It is demonstrated that laser cleaning, which with appropriate laser energy density and scanning times, can removal the mildew form the rice paper without any damage.
