Laser-induced breakdown spectroscopy (LIBS) is a versatile analytical technique for element determination in solids, liquids, and gases. However, LIBS suffers from low detection sensitivity and high relative standard deviation (RSD), restricting its large-scale applications. the process of a physical sampling can, in some cases, compromise the mechanical strength of the component under examination. It should be considered that too large laser energy is bound to cause damage to samples which cannot be tolerated in the process of safe production in the nuclear industry. It is necessary to find a method to obtain high elemental signal intensity in low energy laser.

微波等离子体炬调制对激光诱导击穿光谱的信号质量改善


激光诱导击穿光谱 （LIBS） 是一种用于测定固体、液体和气体中元素的通用分析技术。然而，LIBS 的检测灵敏度低，相对标准偏差 （RSD） 高，限制了其大规模应用。在某些情况下，物理采样过程可能会损害被测组件的机械强度。应该考虑到，过大的激光能量必然会对样品造成损害，这在核工业的安全生产过程中是不能容忍的。有必要找到一种在低能量激光器中获得高元素信号强度的方法。
