Recent proposals have shown that by properly designed laser arrangements or lattice setups it is possible to induce artificial gauge fields, which can even be non-Abelian. In this contribution, we will first discuss simple laser setups that allow the creation of non-Abelian gauge fields. Then the Landau levels of cold atomic gases in non-Abelian gauge fields are analyzed. In particular we identify effects on the energy spectrum and density distribution which are purely due to the non-Abelian character of the fields. In a second part, we discuss non-Abelian generalizations of both the Landau and the symmetric gauge, and how these can be generated.
