摘要
为了研究激光与材料相互作用的机制,获得激光等离子体的状态参数,利用XeCl准分子激光器(308nm,200mJ)烧蚀纯铜样品获得等离子体,使用光栅光谱仪获取了激光诱导的纯铜等离子体发射光谱。在局部热力学平衡(LTE)条件近似下,根据特征谱线的相对强度,利用多谱线斜率法,得到了等离子体温度约为1.7×104K。
In order to study the mechanism of laser interacting with materials,the parameters ralated to the laser plasma,the laser plasma is obtained by XeCl laser(308nm,200mJ)ablating copper,the plasma spectra is obtained by grating spectrometer.Under the model of local thermodynamic equilibriumc,the temperature of plasma is deduced to be nearly 1.7×104K,using multi-line slope by the ralative line intensities.
