Laser Induced Breakdown

In this work, the elemental constituents of smoker and nonsmokerteeth samples of human were analyzed by Laser induced breakdownspectroscopy method (LIBS). Many elements have been detected inthe healthy teeth samples, the important once are Ca, P, Mg, Fe, Pband Na. Many differences were found between (female and male)teeth in Ca, P, Mg, Na and Pb contents. The concentrations of mosttoxic elements were found significantly in the smoker group. Themaximum concentrations of toxic elements such as Pb, Cd and Cowere found in older male age above 60 year. Also, it was found thatthe minimum concentrations of trace elements such as Ca, P and Naexist in this age group. From these results it is clear that the LIBStechnique is a powerful tool for fast identification of teeth problems.

Laser Induced Breakdown

Laser-induced breakdown spectroscopy (LIBS) is a powerful technique for quantitative diagnostics of gases. The spatial resolution of LIBS, however, is limited by the volume of plasma. Here femtosecond-nanosecond dual-pulsed LIBS was demonstrated. Using this method, the breakdown threshold was reduced by 80%, and decay of continuous radiation was shortened. In addition, the volume of the plasma was shrunk by 85% and hence, the spatial resolution of LIBS was significantly improved.
