摘要:通过对脉冲Nd∶YAG激光烧蚀金属Cu过程中的烧蚀靶和收集板上电荷的时间分辩测量,分析了烧蚀过程中电子与离子从烧蚀靶表面的发射特征。结合连续辐射强度的时空分布,讨论了激光诱导等离子体连续辐射的产生机理,认为连续辐射是以电子的轫致辐射为主要机制。
By time-resolved measurement of charge in ablation target and collector the emission characters of electron and ion produced by pulsed Nd∶YAG laser ablation of metal Cu is investigated.The emission characters of election and ion is investigated,and combining the time-resolved of the charge with time-resolved intensity distribution of the continuum emission,Bremsstrahlung of electron is the primary mechanism of the continuum.
