Laser Induced Breakdown

A single-beam-splitting approach was used to enhance the signal intensity of LIBS under the extreme condition of a laser beam grazing the surface of non-flat samples. We investigated the time-resolved characteristics of laser-induced plasma under single- and split beam modes.

Laser Induced Breakdown

Laser-induced breakdown spectroscopy has been used to determine carbon content in steel. The plasma was formed by focusing a Nd:YAG laser on the sample surface. With the use of time-resolved spectroscopy and generation of the plasma in nitrogen atmosphere, a precision of 1.6% and a detection limit of 65 ppm have been obtained. These values are similar to those of other accurate conventional techniques. Matrix effects for the studied steels are reduced to a small slope difference between the calibration curves for stainless and nonstainless steels.
