TLDR
An efficient spontaneous-force laser trap of neutral atoms without standing waves is demonstrated by using the Ne 1s(5) metastable state and the dynamics of atomic motion from the deceleration stage to the trap is discussed.Abstract:
An efficient spontaneous-force laser trap of neutral atoms without standing waves is demonstrated by using the Ne 1s5 metastable state. The metastable Ne beam is decelerated by a laser by using Zeeman tuning and is trapped in a trap consisting of a quadrupole magnetic field and four laser beams in a tetrahedral configuration. The dynamics of atomic motion from the deceleration stage to the trap is discussed.read more

TL;DR: An atom chip is realized that enables the integration of laser cooling and trapping into a compact apparatus, and delivers ten thousand times more atoms than previous magneto-optical traps with microfabricated optics and can reach sub-Doppler temperatures.

Cooling and trapping of neutral atoms
TL;DR: In this paper, a review of the techniques for laser cooling and trapping of neutral atoms are described. But it was not until the 1980's that optical momentum transfer was used to cool and trap neutral atoms.

Trapping of neutral sodium atoms with radiation pressure
TL;DR: The confinement and cooling of an optically dense cloud of neutral sodium atoms by radiation pressure was reported, provided by three retroreflected laser beams propagating along orthogonal axes, with a weak magnetic field used to distinguish between the beams.

Experimental observation of optically trapped atoms.
TL;DR: The first observation of optically trapped atoms is reported, with estimates that about 500 atoms are confined in a volume of about ${10}^{3}$ \ensuremath{\mu}$ m3 at a density of about £10^{11}$-${10]^{12}$ and in good quantitative agreement with theoretical expectations.

Laser Deceleration of an Atomic Beam
TL;DR: In this article, the deceleration and velocity bunching of Na atoms in an atomic beam have been observed, caused by absorption of counter-propagating resonant laser light.
