Optimisation of experimental parameters for double-pulse LIBS
Roščák, Michal ; Novotný, Karel (oponent) ; Kaiser, Jozef (vedoucí práce)
Diploma thesis presents the description of laser induced breakdown spectroscopy (LIBS) analytical method. The possibility to decrease LIBS detection limits using double pulse LIBS (DP-LIBS) is also detailed. Properties of laser induced plasma (LIP) are discussed. Thesis describes the optimisation process of DP-LIBS setup at laser spectroscopy laboratory of Faculty of Mechanical Engineering, Brno University of Technology. Optimisation was carried out for detection of chrome in steel with respect to detection limits and ablation crater size. Optimised DP-LIBS setup is appropriate for mapping chrome distribution in steel samples.
Design of an optical system for expanding of the Nd:YAG laser beam in the Laser Induced Breakdown Spectroscopy (LIBS) setup
Roščák, Michal ; Antoš, Martin (oponent) ; Kaiser, Jozef (vedoucí práce)
Purpose of this bachelor thesis is to design of an telescope for expanding the Nd:YAG laser gauss beam used in LIBS aparature. Intesity of the radiation around centre is approximately same and therefore is useful for focusation on sample. Designed telescope consists of two lenses. Distance between them can be adjusted by fine screw thread for attributes correction of the expanded beam. The aparature is designed with respect for system optical aberrations and final size of the telescope.
