Characteristic of spatiotemporal evolution of hydrogen isotope in laser-induced plasma under low-pressure environment

Characteristics of laser-induced plasma generated in water and in air with different nanosecond laser pulse durations

“…2 It has developed into an important technique in analytical chemistry with the advantages of multi-elemental analysis, no or little sample preparation, and real-time and rapid analysis. LIBS has been used in various elds, especially under extreme conditions, including deep space, 3,4 high temperature, 5 low pressure or a vacuum 6,7 etc., where in situ and non-contact detection capabilities are in high demand. However, the analytical performance of LIBS is oen limited due to the transient nature of the plasma.…”
