SUMMARY:Continuous loading of ultracold ground state molecules in a di
 pole trap using a single light beam\, Atomic Physics Seminar\, Profess
 or Luis Marcassa\, Universidade de Sao Paulo\, Brazil
DESCRIPTION:We have developed an approach to continuously load ultraco
 ld 85Rb2 vibrational ground state molecules into a crossed optical dip
 ole trap from a magneto-optical trap. The technique relies on a single
  high-power light beam with a broad spectrum superimposed onto a narro
 w peak at an energy of about 9400 cm-1. This single laser source perfo
 rms all the required steps\, namely the photoassociation\, vibrational
  cooling\, and optical trapping of the molecules. We have also perform
 ed depletion spectroscopy\, which allows us to determine that 75% of t
 he vX= 0 molecules are in J= 0\, 1 and 2 rotational states. The lifeti
 me of the ultracold molecules in the optical dipole trap is limited by
  off-resonant light scattering to about 70 ms. The proposed technique 
 may open perspectives for the formation of new molecular species in th
 e ultracold domain\, which are not yet accessible by well-established 
 approaches.
