This bachelor thesis describes the setup of a lithium lasersystem for an experiment with fermionic lithium and bosonic sodium and the cooling of lithium atoms with a Zeeman slower as well as the trapping with a magneto-optical trap. The theory part in the beginning summarizes the basic features of the atomic structure of alkali atoms. Subsequently, the experimental implementation of a frequency stabilized diode laser for lithium, which has a stability of approximately 1MHz, is shown. The basics of laser cooling using a Zeeman slower are explained and for our case with lithium specified. Besides, a commonly used method to probe atom clouds, the absorption imaging method, is explained. Finally, our experimental results are shown, in which we optimise the size of our trapped atom cloud with the parameters the slower provides us with. In addition, our total atom number is determined by capturing the fluorescence on a photodiode and via absorption imaging, whereas the latter one is presented in detail in this thesis. |
