Abstract

We have been examining the emission spectra from laser-induced breakdown plasmas as a technique for atomic identification. The concept is straightforward and the apparatus simple (see Fig. 1); the plasma is a bright source requiring little subtlety to resolve. By adding time resolution to the detector, one moves from LIBS (Laser-Induced Breakdown Spectroscopy) to TRELIBS (Time-Resolved LIBS) and for most cases gains considerable sensitivity. Our applications have mostly been aimed at the detection of trace constituents. The only previous use of this technique of which we are aware was a measurement of the fuel/air ratios in combustion.
