Abstract :
The authors have developed an integrated remote laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy system for measuring both LIBS and Raman spectra. The system has been used for analyzing both Raman and LIBS spectra of minerals in air. These experiments demonstrate that by focusing a 532nm Nd:YAG pulsed laser beam with a 5× beam expander to a 1.5 mm diameter spot on a sample surface located at 15 meters away, it is possible to identify the compositions of the sample by using this remote LIBS and Raman spectrum detection system.
