Abstract
Laser-induced breakdown spectroscopy (LIBS) offers several advantages, including simultaneous multi-element detection, a simple structure, rapid detection speed, and no impact on sample morphology. Recent advancements in LIBS technology have focused primarily on signal enhancement and improved data analysis, with imaging techniques serving as the main method for exploring plasma characteristics. In this study, we investigate the application of a femtosecond (fs) double-pulse scheme to enhance the analytical performance of LIBS under varying polarization and wavelength conditions. Our results show that combining double pulses with polarization allows for the study of the plasma expansion process. This research presents new insights into the development of LIBS by adjusting the relationship between the polarization state and wavelength, offering a relatively simple method for improving LIBS technology.
