Laser-induced breakdown spectroscopy (LIBS) is an analytical detection technique and sensor technology that is undergoing a dramatic transformation in terms of hardware, software, and application areas. It is a field that is significantly maturing yet at the same time expanding dramatically into new areas. The genesis of laser spark spectrochemistry (the core of the LIBS technique) tracks the development of the laser, as the first pulsed lasers were found to be capable of producing sparks in air and on surfaces. Inevitably, spectral analysis of these laser-induced sparks became an area of study. The current manifestations of this technique aimed toward the purpose of chemical analysis can be traced to the works of Radziemski, Cremers, and colleagues at Los Alamos National Laboratory in the early 1980s. It is from this group that the acronym LIBS first appeared. The thrust and refinement of LIBS as a chemical analytical tool was made possible by continuous advances in component instrumentation, namely the intensified charge-coupled device array detectors and more mature and more reliable laser sources. The array detectors were very important in that they allowed the capture of multiple emission lines from a single LIBS event.
