Bismut, B. Pasquiou, D. Ciampini, B. Laburthe-Tolra, E. Maréchal, L. Vernac, O. Gorceix] We report on a strategy to maximize the number of chromium atoms transferred from a magneto-optical trap into an optical trap through accumulation in metastable states via strong optical pumping. We analyse how the number of atoms in a chromium Bose-Einstein condensate can be raised by a proper handling of the metastable state populations. Four laser diodes have been implemented to address the four levels that are populated during the MOT phase. The individual importance of each state is specified. To stabilize two of our laser diode, we have developed a simple ultrastable passive reference cavity whose long term stability is better than 1MHz. Springer-Verlag, 2010 Bismut G.
