Abstract

Laser-induced breakdown spectroscopy (LIBS) is a laser-based, advanced diagnostic technique for measuring the concentration of various elements in the test medium.1-3 In LIBS, a pulsed laser beam is focused at the test point to produce a spark. The spark in the focal region generates a high density plasma which atomizes and electronically excites the various atomic elements in the test volume. Atomic emission from the plasma is collected and analyzed to obtained the concentration of the atomic species in the test medium.
