Laser-induced breakdown spectroscopy (LIBS) has been investigated for the detection of energetic materials. After an initial survey of explosives and propellants, key elemental and molecular emission lines in the LIBS spectra were identified. Techniques for improving the sensitivity and selectivity of LIBS for explosives detection, such as the use of an argon buffer gas and double pulse LIBS, have been investigated with laboratory and field-portable instruments. We present results demonstrating ...
