Laser de CO2.
Abstract in Portuguese
Neste trabalho apresentamos a construção de uma armadilha de dipolo com laser de CO2 que envolveu a utilização de novas e modernas tecnologias nunca utilizadas pelo nosso grupo até então. Podemos destacar a construção de uma nova câmara de aprisionamento com grande acesso óptico, getters como fonte de átomos e um laser de CO2 de alta potência e sua óptica. Demonstramos o aprisionamento de átomos de 85Rb em uma armadilha magnética e magneto-óptica e analisamos sua dinâmica, obtendo resultados das taxas de perdas provocadas por colisões entre átomos aprisionados e átomos quentes provenientes do vapor de fundo e do getter. Este entendimento será importante na implementação da técnica totalmente óptica de aprisionamento simultâneo de átomos de Rb e moléculas de Rb2.

Abstract in English
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.
