What is it?
Laser-induced breakdown spectroscopy (LIBS) is a form of Atomic emission spectrometry (AES) technique involving laser-generated plasma which combines all the required processes for optical emission spectrometry: simultaneous sample vaporization, atomization and excitation. LIBS is inherently attractive and useful because of its capability to detect, identify, and quantify the chemical composition of any material in any form (e.g. gas, liquid, solid, conductive or non-conductive).

Basically, a LIBS measurement is carried out by forming a plasma on or in the sample and then collecting and spectrally analyzing the plasma light. Since the plasma is formed by optical means, the LIBS technique offers unique features compared to conventional techniques that use an adjacent physical device. Among these attributes is its ability to interrogate samples in situ and remotely without preparation of the sample, and to realize fast analysis with the capability to determine nearly all elements of the periodic table. Recently, the success of the LIBS probe on the Curosity Mars rover has renewed interest in the method for a wide range of applications especially in geology and geochemistry.
