1. Calcium magneto-optical trap loaded from a decelerated atomic beam
We describe a new system for laser cooling and trapping of neutral Calcium atoms employing the ¹S0 -¹ P1 resonant transition at 423 nm. An on-axis magneto-optical trap (MOT) is loaded from a Zeeman decelerated atomic beam. When a single laser is used, in order to avoid perturbation of the trap by the deceleration laser beam, this one has been tightly focus

2. Desenvolvimento de fontes laser, espectroscopia de alta resolução e resfriamento e aprisionamento magneto-optico de atomos de calcio
In this work, we report on an experimental system for laser cooling and magneto-optical trapping of calcium atoms, the development of the laser sources for this system, and a spectroscopic analysis of calcium transitions in hollow cathode electric discharges. In the case of calcium, the most efficient optical transition for the atom motion manipulation by ra

3. Desacelaração de césio pela técnica de sintonia Zeeman / Deceleration of cesium by Zeeman tunning technique
Neste trabalho pela primeira vez, desaceleramos um feixe de Cs pela Técnica de Sintonia Zeeman. Usamos um laser de diodo contrapropagante ao feixe atômico. Essa técnica se baseia na utilização de um campo magnético de perfil espacial parabólico para compensar o efeito Doppler e manter o átomo ressonante com o laser durante o processo de desaceleraç�

4. Construção de um sistema experimental para desaceleração de átomos. / Construction of an experimental system for stopping atoms.
This work presents the development and test of an experimental set-up which allows to produce a very strong slow motion atomic beam. We discuss the calculation and construction of the solenoid to compensate the Doppler effect arising during the deceleration process, vacuum chambers, the oven which produces the atomic beam and the optical system used. We have

5. Simulation of the process of decelerating atoms by the Zeeman-tuning technique / Simulação do processo de desaceleração de átomos pela técnica de ajustamento Zeeman
The main purpose of this work is, adopting a numerical simulation approach, to understand the laser deceleration of an atomic beam by means 0f the kown Zeeman tuning technique. Our numerical calculations are able to reproduce the fundamental features of the experimental results already obtained. We also present a simple analytical model incorporating the bas
