通过激光烧蚀浸入水中的铜金属板观察到脉冲持续时间对 Cu I 发射线轮廓的影响。通过照射持续时间长于40 ns的脉冲，可以获得具有清晰的窄发射线的Cu原子的光谱轮廓，而发射光谱总是因20 ns脉冲的照射而受到展宽和自吸收的影响。结果表明，使用长持续时间脉冲可以对与大量液体接触的固体表面进行原位元素分析。 (c) 2006 年美国物理研究所。
The effect of pulse duration upon the line profile of Cu I emission observed by laser ablation of a copper metal plate immersed in water has been examined. By irradiating a pulse with the duration longer than 40 ns the spectral profile with clear narrow emission lines of Cu atoms is obtained, while the emission spectra always suffer from broadening and self-absorption by the irradiation of the 20 ns pulse for the ablation. The results show that the use of a long-duration pulse enables in situ elemental analysis of the solid surface in contact with a bulk liquid. (c) 2006 American Institute of Physics.
