偏振分辨激光诱导击穿光谱（PRLIBS）技术通过在探测器前放置起偏器，可以显著降低激光等离子体的偏振辐射，是提高激光诱导击穿光谱应用中谱线与连续谱线比的有力工具。结果表明，从等离子体产生的连续发射通过烧蚀铝样品纳秒激光脉冲比离散线发射与单脉冲PRLIBS技术更偏振。系统地研究了激光能量密度和探测角对铝偏振光谱的影响。偏振谱随激光能量密度变化的计算结果与实验结果一致。
The polarization-resolved laser-induced breakdown spectroscopy (PRLIBS) technique, which can significantly reduce the polarized emission from laser plasma by placing a polarizer in front of the detector, is a powerful tool to improve the line-to-continuum ratio in LIBS applications. It is shown that the continuum emission from the plasma produced through ablating an Al sample by nanosecond laser pulses is much more polarized than the discrete line emission with the single-pulse PRLIBS technique. The effects of laser fluence and detection angle on the Al polarization spectrum are systematically explored experimentally. The calculated result of the polarization spectrum as a function of laser fluence shows that it is in agreement with the experimental observations.
