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. |
