laser cooling

n.
The reduction of kinetic energy of atoms or molecules by means of a tunable laser, which, when set at a certain frequency, will cause approaching atoms that absorb photons to lose momentum.

The Cold Atom Laboratory (CAL), which is about the size of a small refrigerator, uses laser cooling to produce a temperature 10 billion times colder than the vacuum of space.
The team used a new process of laser cooling to cool a cloud of rubidium atoms all the way from room temperature to 1 microkelvin, or less than one-millionth of a degree above absolute zero.
By linking the laser cooling of the crystal resonator with the spin of the internal defect it should be possible to monitor the changes in spin configuration of the internal defect -- these changes are called Bohr spin quantum jumps -- via the mechanical resonator's vibrations.
Her experiments use laser cooling, magnetic trapping and evaporative cooling to reach temperatures below one microKelvin, where quantum statistics dominate the behavior of atoms.
To produce and maintain such temperatures, physicists normally use laser cooling. But for this system, that would pose a problem because laser light is also used to create the timekeeping oscillations.
Coverage overlaps with the many texts that cover laser spectroscopy and quantum optics, but this text is distinguished by discussion of topics from a variety of viewpoints and by inclusion of topics not readily available in other introductory texts such as atom optics and interferometry, optical pumping, light scattering, and sub-Doppler laser cooling. To keep the volume a manageable size the authors have selected a limited number of fundamental applications and have not reproduced experimental data.
Britestar II is a laser designation and long-range thermal imager system with an integrated boresight module to provide in-flight laser aim-point accuracy validation, and an integrated laser cooling system to ensure a continuous laser firing capability.
Phillips, who shared the 1997 prize in physics for his work on laser cooling technology, is currently working on research that could contribute to development of a quantum computer.
Recent developments in laser cooling and trapping at the National Institute of Standards and Technology, Gaithersburg, Md., have produced some interesting results pertaining to the "rare earth" element erbium.
Alfa Laval has introduced the latest new model of its AlfaNova[TM] fusion-bonded heat exchanger, the AlfaNova[TM] 14, for duties such as process cooling, hydraulic oil cooling, laser cooling, hygienic/sanitary duties, water/water cooling and heating.
