The aim of the project is to combine a pulsed laser and a high-resolution spectrometer to construct a system for chemical analysis. The analysis is based on laser ablation and plasma generation in argon atmosphere, together with synchronized detection and analysis of the emitted plasma radiation. This methodology is also known as laser-induced breakdown spectroscopy (LIBS).
The project will involve reviewing selected LIBS literature and designing and constructing a system for infrared laser excitation, detection of plasma emission, gas flow control, etc. Particular focus will be on system design features and sample preparation that influence the repeatability of measured signals. The students will become familiar with the proper laser safety protocols and the basics of elemental analysis by plasma spectroscopy.
