RESUMO

In this work we present the construction of an optical dipole trap using a CO2 laser, which involves the use of news and modern technologies never utilized by our group up to now. We have builded a new trap chamber with large optical access, used atomic dispensers as an atomic source and a high power CO2 laser and its optical components. We have demonstrated trapping and cooling of 85 Rb in a magneto-optical trap as well as and magnetic trap. By analyze its dynamic, we have obtained results on the collisional loss rates between trapped atoms imprisoned and hot atoms originating from the background gas. This understanding will be important in the implementation of the technical one entirely optical trap for Rb atoms as well as Rb2 molecules.
