摘要: 采用光偏转法测量了3种粗糙度的黄铜样品在潮湿环境与干燥环境下的激光烧蚀阈值.结果表明,两种烧蚀环境下,表面粗糙度越大,烧蚀阈值越低;同一粗糙度时,潮湿环境比干燥环境烧蚀阈值低.说明粗糙表面及潮湿表面对光的吸收率大,通过同一泵浦能量密度下冲击波渡越时间的不同而得到证明.

Abstract: Based on the principle of probe beam deflection,the ablation thresholds of three copper samples with different roughness are measured in moist and dry environment.The results show that,in the two kinds of environment,the larger the roughness,the lower the ablation threshold.When the roughness and the pump energy fluence are all equal,the ablation threshold is lower in the moist environment than in the dry environment.This phenomenon indicates that the rough and moist surface has big absorption coefficient to pump energy,which can be proved by the different transit time in the case of the same pump energy fluence.
