1. Desenvolvimento de um laser de Nd:YLF bombeado por diodo laser e duplicado em frequencia para 657 nm / Development of a diode pumped Nd:YLF laser, frency doubled to 657 nm
Atomic clocks are used today in a number of scientific and technological applications, ranging from tests of relativity, or variations of fundamental constants, to the use in navigation and telecommunication. The next generation of such high precision devices will be based on optical transitions of suitable laser cooled and trapped atoms. In this work we des

2. Ramsey Spectroscopy in an atomic fountain / Espectroscopia Ramsey em um chafariz atômico
We present some relevant aspects for the realization of a 133Cs fountain, intended to operate as a primary frequency standard to realize the definition of the second. The main goal of this work is the optimization of the experimental setup of the atomic fountain in its most critical parts: the interaction region and the detection system. Furthermore, the sev

3. The 61S0-63P0 transition in thallium isotope ion 204Tl+: A superior atomic clock
Experimental and theoretical studies of the forbidden J = 0 → J′ = 0 optical transition 61S0-63P0 in the odd Hg isotopes are in the literature. From this work natural width and quadratic Zeeman effect have been estimated for the same line in the isoelectronic, even thallium ion 204Tl+, which has a very small nuclear magnetic moment. For the mF = 0 → 0
