Laser cooling of the SiO+ molecular ion: A theoretical contribution

Chemistry Physics, 2019
The feasibility of laser-cooling SiO+ molecular ion is studied by using ab initio methods. The electronic structures of 14 Λ-S states and 30 Ω states of SiO+ are computed by means of high-level configuration interaction method (including Davidson ...

Laser cooling in a squeezed vacuum

Physical Review A, 1991
In this paper, the use of squeezed light in laser cooling is investigated. We find that in a traveling-wave laser field, a two-level atom in a squeezed vacuum cannot be cooled to a lower temperature than in normal vacuum. For a two-level atom in a standing-wave laser field, if it is tuned from the resonant region, the conclusion is the same as in the ...

Laser-cooling with an intermediate electronic state: Theoretical prediction on bismuth hydride.

Journal of Chemical Physics, 2019
The possibility of laser cooling of bismuth hydride (BiH) molecules has been investigated based on high-level ab initio calculations by considering the core-valence and the spin-orbit coupling (SOC) effects.

Laser Cooling in an Optical Shaker

Physical Review Letters, 2005
We propose a novel generic approach to laser cooling based on the nonresonant interactions of atoms and molecules with optical standing waves experiencing sudden phase jumps. The technique, termed "optical shaking," combines the elements of stochastic cooling and Sisyphus cooling.

Laser cooling and trapping of atoms

Optics News, 1986
We recently demonstrated the first optical trapping of atoms. An important prelude to that work was our earlier demonstration of ‘‘optical molasses,’’ a technique for creating a long‐lived collection of ultra‐cold atoms. This paper presents a pedagogical discussion of those experiments and of the background material needed to understand them.

Laser cooling of thallium chloride: A theoretical investigation.

Journal of Chemical Physics, 2018
The possibility of laser cooling of thallium chloride (TlCl) molecules has been investigated based on high-level ab initio calculations with the consideration of the core-valence and the spin-orbit coupling (SOC) effects.

Laser cooling of lithium using relay chirp cooling

Optics Letters, 1992
We demonstrate a chirp-cooling technique that uses a laser with multiple FM sidebands to slow lithium atoms from initial velocities of as much as 1880 m/s to final velocities near zero. Compared with the use of a single sideband, this multisideband technique significantly reduces FM bandwidth requirements and provides a greater flux of slowed atoms.

Laser cooling and trapping of francium

2005
An apparatus to produce francium atoms and to trap them in a magneto-optical trap (MOT) has been set up at the Legnaro INFN National Laboratories (Italy). A detailed description of the main parts of the apparatus is given together with step-by-step measurements characterizing the production, transport, neutralization, and trapping of the radioactive ...
