Comparison of Laser-Induced Breakdown Spectra of Organic Compounds with Irradiation at 1.5 and 1.064 micrometers
A comprehensive investigation of laser-induced breakdown spectroscopy (LIBS) at 1.500 micrometers of residues of six organic compounds (anthracene, caffeine, glucose, 1,3-dinitrobenzene, 2,4-dinitrophenol, and 2,4-dinitrotoluene) on aluminum substrates is presented and compared with LIBS at the Nd:Y...

| description | A comprehensive investigation of laser-induced breakdown spectroscopy (LIBS) at 1.500 micrometers of residues of six organic compounds (anthracene, caffeine, glucose, 1,3-dinitrobenzene, 2,4-dinitrophenol, and 2,4-dinitrotoluene) on aluminum substrates is presented and compared with LIBS at the Nd:YAG fundamental wavelength of 1.064 micrometers. The overall emission intensities were found to be smaller at 1.500 micrometers than at 1:064 micrometers, and the ratios of C2 and CN molecular emissions to the H atomic emissions were observed to be less. Possible reasons for the observed differences in LIBS at 1.064 micrometers versus 1.500 micrometers are discussed.
