Abstract: This work provides a review of the capabilities and applications of laser-induced breakdown spectroscopy (LIBS) at the U.S. Army Research Laboratory (ARL). By coupling advances in LIBS hardware and analysis software, ARL has expanded the capabilities of LIBS significantly. LIBS uses a focused, pulsed laser to ablate a target material, generating a transient microplasma which emits light characteristic of the sample composition. It is a real-time sensor technology which requires no sample preparation and provides universal materials detection for solids, liquids, and aerosols. Applications investigated at ARL in recent years include the standoff detection of explosive residues and other hazardous materials, plastic landmine discrimination, and material characterization of various metal alloys and polymers.
