Coherent Atomic Manipulation and Cooling: Interferometric Laser
Laser Manipulation of Atoms and Ions - Ennio Arimondo, W D
The number of laser units required makes the achievable minimum size and power of the instrument challenging, especially for space applications. The laser system must also be able to meet the requirements of a complex, modern cold atom system; it needs to cool atomic clouds launched from the atomic source to a 3D kinetic temperature in the range of a few mK, in a single magnetic substate, and in a narrow range of velocities along the axis of the laser interferometer.

Laser cooling and trapping of metastable atoms.
and compresses the velocity distribution (i.e., cooling the atom sample). A single laser beam is sufficient to cool a sample of trapped atoms or ions; however, free atoms must be irradiated with laser beams from all di-rections. For atoms with velocities that cause Doppler shifts comparable to the natural transition width (typi- Inherent advantages of atom interferometry 1. Laser cooling and manipulation techniques extend the interferometer measurement time, defined as the drift time of an atom through the interferometer, by orders of magnitude over interferometers based on photons, electrons or neutrons. 2. Wavelength of matter waves is much shorter, leading to 2020-02-24 The sensor consists of a dual Mach-Zehnder-type atom interferometer operated with laser-cooled $^{87}$Rb.
In this example, a hot wire detector detects the fringe pattern. S254 Wieman, Pritchard, and Wineland: Atom cooling, trapping, and quantum

We also aim to have one and only one atom at each site over 100 consecutive sites so that they constitutes a zero-entropy system well suited for initial state for quantum information processings. 2019-10-10 · Sources based on alkaline atoms (e.g. Li, Na, K, Rb, Cs) are widely used in cold-atom experiments and have shown excellent performance. Due to their rather simple energy levels structure, there are several applicable laser cooling schemes applicable and evaporative cooling to degeneracy is possible both in magnetic and optical potentials [19–22].
