利用飞秒偏振分辨激光诱导击穿光谱（fs-PRLIBS）对铝样品进行了分析。我们比较得到的光谱与纳秒PRLIBS（ns-PRLIBS）。fs-PRLIBS的主要特点是较低的等离子体温度导致低水平的连续谱，并且从环境气体中没有检测到物种。此外，fs-PRLIBS获得的信号显示出比ns-PRLIBS更高的稳定性。然而，在ns-PRLIBS光谱中检测到更多的元素。
Aluminum samples have been analyzed by femtosecond polarization-resolved laser-induced breakdown spectroscopy (fs-PRLIBS). We compare the obtained spectra with those obtained from nanosecond PRLIBS (ns-PRLIBS). The main specific features of fs-PRLIBS are that a lower plasma temperature leads to a low level of continuum and no species are detected from the ambient gas. Furthermore, signals obtained by fs-PRLIBS show a higher stability than those of ns-PRLIBS. However, more elements are detected in the ns-PRLIBS spectra.
