SUMMARY:All optical production of a 39K BEC - Guillaume Salomon (Institut 
 Optique\, France)

DESCRIPTION:Disorder is ubiquitous in condensed matter systems and it has 
 proved to profoundly affect the transport properties. The main goal of our
  experiment is to observe the inhibition of transport due to disorder in t
 wo dimensions\, a phenomenon called Anderson localisation. However it requ
 ires very low temperature and weekly interacting gases. In this talk I wil
 l present the all optical production of a 39K BEC by directly loading a di
 pole trap from the molasses. I will describe in details the gray molasses 
 technique that allows to load a high number of atoms in an optical trap an
 d the procedure to achieve an efficient evaporative cooling to Bose Einste
 in condensation. I will finish my talk by describing the short term perspe
 ctive to observe coherent effects in the momentum distribution of a 2D dis
 ordered Bose gas
