A variety of methods have been found for cooling isolated atoms and ions to lower temperatures (Wine-land and Itano, 1987; Wieman and Chu, 1989; Cohen-Tannoudji and Phillips, 1990). These include sub-Doppler laser cooling, evaporative cooling, and laser ‘‘sideband’’ cooling. Sub-Doppler laser cooling uses Different atomic cooling techniques exist, e.g. Doppler cooling, Sub–Doppler technique (used when the Doppler limit is reached – natural linewidth of the atomic transition), and atom evaporation in a Bose-Einstein condensate to slow the atom further.
Teletype for Atom. Great things happen when developers work together—from teaching and sharing knowledge to building better software. Teletype for Atom makes collaborating on code just as easy as it is to code alone, right from your editor.

One of the most successful applications of cold-atom sources has been the development of atomic clocks. Small, portable frequency standards, are a key cog in GPS technology. Due to the delicate nature of the quantum states, ultra-cold atoms make for incredibly precise sensors as well.

The principal applications of atom optics have been in the creation and use of atom interferometers (Ber-man, 1997), and for atom lithography—the deposition of precise patterns of atoms on surfaces (Thywissen et al., 1997). The principle tools of atom optics have been light forces and nanofabricated mechanical structures, and Atomic Trapping and Cooling Laser cooling and trapping is the ability to cool atoms down to unprecedented kinetic temperatures, and to confine and support isolated atoms in “atom traps”.
