Spectral narrowing and frequency pulling of multi-mode, high power diodes Master thesis available! Transfer cavity system locking multiple wavelengths on a potassium frequency standard Master thesis available! A diode laser system for lasercooling of diatomic molecules. First double BECs. Both, 23Na and 39K are condensed at the same spot at the same time. New PhD student! Philipp joined our team. Welcome! First Na-K Feshbach Spectroscopy We managed to get nice signals both on 23Na and 39K in the optical dipole trap and saw first losses due to three body interactions. First Na BEC We managed to load sodium atoms to the crossed optical dipole trap and evaporate them. We end up with a nice bimodal distribution. Paper published! Our electrode paper is on arXiv and got accepted for publication. Matthias defended his thesis! Congratulations! Vacuum Chamber Finally! After a long struggle, we finally got rid of our weird vacuum problems! Now, the lifetime of the atomic ensembles is no longer degrading over a period of several months – but stable in the ... Paper published! Our paper on the reaction kinetics of chemical processes occurring in the ultracold regime has been published. Paper published! Our paper on the modelling and the experimental demonstration of a two-photon coherent transfer path from ultracold Na and K atoms to ultracold ground state molecules has been published. Finally, we can move into our labs!
