Calculation of an Optical setup for a LIBS system

Abstract

In this work we will represent the calculation for an optical LIBS system, as well as the parameters for the beam characterization. On the realized simulation, the beam was treated with the wave optics theory and its propagation with the paraxial approximation. It was described as a beam of Gaussian intensity profile and its propagation was acquired through the ABCD's law. Our results have showed the appropriated lens to hold a LIBS sign for different kinds of materials, depending on their bond cleavage. Also, we have showed a table with typical values of focus lens, used in LIBS setups, and its respective irradiance.

“…The laser-induced breakdown spectroscopy (LIBS) [15] of the AE sample was performed using a Nd:YAG laser with 200 mJ per pulse and 10 ns temporal width. A spectrometer (Stellarnet, Florida, USA) operating from 190 to 300 nm with a 0.2 nm optical resolution was used.…”
