Laser induced breakdown spectroscopy (LIBS) has been used to identify the various glass and crystal samples. In LIBS technique, a high energy beam from a Q- switched pulsed Nd: YAG laser is used to ablate the sample surface. The emissions from the plasma is carried to Ocean Optics spectrometer (LIBS2500 plus) by group of optical fibers. The spectrometer can analyze in the spectral range of 200 nm to 980 nm at 0.1 nm resolution. The spectrum were recorded by using OOILIBS plus (v1.0) software. Ten individual spectrums of each sample were averaged to get a final spectrum for analysis. The LIBS technique has advantage that no sample preparation is required and laser light causes extremely minimal damage to the sample surface.
