Nd:YAG激光的聚焦辐射用于烧蚀和从导电和不导电固体中产生自由样品原子用于分析目的。微等离子体是在减压氩气缓冲气氛中产生的。为了提高分析谱线的强度，在原子化过程完成后，用第二次Nd:YAG激光对微等离子体进行再加热。对玻璃和钢样品中的铝和锰，以及玻璃、铜和铝样品中的镁和锰，通过内部标准化可以得到一个共同的校准曲线。
Focused radiation of a Nd:YAG laser was used for ablation and production of free sample atoms from electrically conducting and nonconducting solids for analytical purposes. The microplasmas were generated in an argon buffer gas atmosphere at reduced pressure. In order to increase the intensities of analyte lines the microplasmas were reheated by a second Nd:YAG laser after the process of atomization was completed. It is demonstrated for aluminum and manganese in glass and steel samples and for magnesium and manganese in glass, copper, and aluminum that by internal standardization a common calibration curve can be obtained.
