SUMMARY: This thesis focuses on beam shaping of laser light, altering it to a more complex structured field. The aim of this dissertation is to be split into two parts. Firstly, it was set to explore and investigate near-infrared laser beam shaping capabilities using the geometric phase elements, applying them for the enhancement of various material micromachining cases. Secondly, the aim of the research was expanded by transferring the knowledge of beam shaping and material micromachining to produce structured terahertz radiation beams by manufacturing different shaping elements with potential application in imaging.
