The Legnaro Francium Magneto-Optical Trap

Hyperfine Interactions, 2003
Laser cooling and trapping of radioactive atoms represent the new frontier in atomic physics and a new powerful tool in nuclear physics. We are setting up at the INFN-Legnaro National Laboratories a laser cooling facility that has as a first goal the realization of a 210Fr magneto-optical trap. The general outline of the experiment and the improvements

Spectroscopy on a modulated magneto-optical trap

Optics Letters, 1998
We demonstrate a new type of high-resolution two-photon frequency modulation (FM) spectroscopy with cold atoms in a magneto-optical trap. Instead of modulating the probe as in ordinary FM spectroscopy, we modulate the trap itself by FM of the trapping beams.

Multiply loaded magneto-optical trap

Optics Letters, 1996
We report a two-chambered, differentially pumped system that permits rapid collection of trapped atoms with a vapor cell magneto-optical trap (MOT) and efficient transfer of these atoms to a second MOT in a lowerpressure chamber. During the transfer the atoms are guided down a long, thin tube by a magnetic potential, with 90(15%) transfer efficiency ...

Magneto-Optical Trap of Cadmium

International Conference on Quantum Information, 2007
We achieve the first magneto-optical trap of Cadmium. When integrated with a nearby ion trap, this allows for the possibility of protecting quantum information from environment perturbations via charge neutralization of trapped ions.

Trapping of Radioactive Atoms: the Legnaro Francium Magneto-Optical Trap

Physica Scripta, 2003
Experiments aimed at laser cooling and trapping of radioactive atoms are nowadays operational at several laboratories. They open up a bridge between atomic and nuclear physics, allowing new precise spectroscopic measurements and detailed analysis of nuclear decay processes.

Magneto-optical trapping of Fermionic potassium atoms

Physical Review A, 1998
We have trapped ${}^{40}\mathrm{K}$ in a vapor-cell magneto-optical trap starting from a natural abundance sample. This rare, weakly radioactive atom is a fermion. The number of trapped atoms is approximately 8000, with a density of $\ensuremath{\sim}{10}^{8}$ atoms/${\mathrm{cm}}^{3}$.

Observation of a single atom in a magneto-optical trap

Optics Letters, 1994
Fluorescence from Cs atoms in a magneto-optical trap is detected under conditions of very low atomic density. Discrete steps are observed in the fluorescent signal versus time and are associated with the arrival and departure of individual trapped atoms.

Improved magneto-optic trapping in a vapor cell

Optics Letters, 1992
We have captured 3.6 x 10(10) cesium atoms in a magneto-optic trap loaded from a vapor cell. The 300-fold increase in the number of trapped atoms compared with that of previous research was accomplished by using larger laser intensities and 4-cm-diameter laser beams. The loading time constant was as short as 0.2 s.

Spatial distribution of atoms in a magneto-optical trap

Physical Review A, 1993
We present a theoretical analysis to explain the origin of different spatial distributions of laser-cooled sodium atoms in a magneto-optical trap. Such distributions, which include spherical clouds, rings, and rings with cores, are attributed to the radiation pressure due to misaligned Gaussian beams acting on each individual atom.

The Blue-Detuned Magneto-Optical Trap

2017
It has been more than 30 years since the first demonstration of a magneto-optical trap (MOT) using sodium atoms. Since then the MOT has revolutionised the field of atomic physics by facilitating the emergence of a broad range of productive avenues of research using atoms prepared at low temperatures and high densities.
