In this project, we intend to set up a plasma-induced spectroscopy experiment through the use of a 150 fs pulse LASER and 1 kHz repetition rate. The focusing of this laser in different materials will allow a spectroscopic analysis of the composition of these. This is because the laser induces the formation of plasma in the material and thereby eject different elements that make up the same. The analysis of the light emitted during this interaction will be collected by a high resolution spectrometer, and due to the emission standards collected, it is possible to stoichiometrically determine the composition.
