Three-dimensional viscous confinement and cooling of atoms by resonance radiation pressure
TLDR
The confinement and cooling of atoms with laser light is reported, in which the atoms are localized in a 0.2 cm volume for a time in excess of 0.1 second and cooled to a temperature of T = 2.4 × 10−4K.Abstract:
The scattering force due to resonance radiation pressure was first detected by Frisch in 1933.[1] Later, Ashkin[2] pointed out that laser light can exert a substantial force suitable for the optical manipulation of atoms, and numerous proposals to cool and trap neutral atoms with laser light.[3] Atoms in an atomic beam have been stopped by light,[4] in which the final velocity spread corresponds to a temperature of 50−100 mK. We report here the confinement and cooling of atoms with laser light, in which the atoms are localized in a 0.2 cm volume for a time in excess of 0.1 second and cooled to a temperature of T = 2.4 × 10−4K.[5]read more

Laser cooling below the Doppler limit by polarization gradients: simple theoretical models
TL;DR: In this article, two cooling mechanisms based on laser polarization gradients are presented, which lead to temperatures well below the Doppler limit, and they work at low laser power when the optical-pumping time between different ground-state sublevels becomes long.
