Calculation of an Optical setup for a LIBS system

In this work we will represent the necessary calculation for the optical setup on a LIBS spectroscopic system, as well as the parameters for the beam characterization. On the realized simulation, the beam was deal 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 necessary 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.
