Observation of Primary and Secondary Enhancement of Emission Spectra From Spatially Confined Laser-Induced Aluminum Plasmas

In this study, four cylindrical cavities with diameters of more than 10 mm are utilized to confine aluminum plasmas to improve the signal intensities of laser-induced breakdown spectroscopy (LIBS). Primary and secondary enhancements of spectra are observed. This phenomenon is attributed to the fact...
