Abstract in Portuguese
Apresentamos a construção de uma Armadilha Magneto-Ótica MOT (Magneto-optical Trap) para átomos de Rubídio. São discutidos os princípios do aprisionamento de átomos neutros, a instrumentação dos lasers de diodo utilizada nesta experiência, e uma caracterização primária da núvem de átomos aprisionados de 'ANTPOT. 85 Rb' e de 'ANTPOT. 87 Rb'. Desenvolvemos um sistema de ampliação ótica multicanal para ser utilizado neste aprisionamento, que denominamos DMOPA (Double Master Oscillator Power Amplifier). Encontramos neste sistema uma instrumentação simples e bem adaptada para o aprisionamento magneto-ótico. Por fim, discutimos as possíveis aplicações da armadilha em nosso laboratório.

Abstract in English
We present the construction of a Magneto-Optical Trap (MOT) for Rubidium Atoms. We discuss the principles of neutral atom trapping, the diode laser instrumentations used in this experiment, and a first caracterization of the trapped clouds of 85 Rb' and 87 Rb' atoms. We also developed a multichannel optical amplification system used for trapping, which we have denominated DMOPA (Double Master Oscillator Power Amplifier). This system is a simple and well adapted instrument dor trapping. Finally, we discuss the intended applications for the MOT in our lab.
