Construction of a lithium quantum gas machine — •Andreas Kerkmann, Jan Mika Jacobsen, Niels Rohweder, Benno Rem, Christof Weitenberg, and Klaus Sengstock — Institut für Laserphysik, Hamburg, Germany

We are setting up a new quantum gas machine for the preparation of small degenerate samples of Lithium atoms. In this poster, we present the planned setup and its current status. The laser system has master lasers on the D2 line for the operation of a MOT and on the D1 line for the operation of a grey molasses. The lasers are locked using spectroscopy in lithium heat pipes. The master lasers then seed TAs, which provide the light for a 2D-MOT and a 3D-MOT. The repumping transition frequency is added by modulating the light with an EOM, thus allowing the operation of lambda-enhanced grey molasses. We plan to directly load a crossed optical dipole trap at 1070 nm from the molasses. The laser system is designed to easily switch between the 6Li and 7Li isotopes.
