A laser system for trapping and cooling of ⁶Li atoms

Abstract

In this thesis, I designed and built a laser system for the trapping and cooling of ⁶Li atoms. The thesis starts explaining a theoretical background of the necessary laser frequencies for the realization of a Zeeman Slower and a 3D MOT. Next it describes the design of the laser system that makes use of a Raman Fiber Amplifier coupled with a Frequency Doubling Cavity and shows the finalized setup. Finally, the thesis delves into the topic of Modulation Transfer Spectroscopy which was used to lock the laser to the D₂ line transition of ⁶Li and shows the spectroscopy setup built for the laser system.
